Looking for help with the Milo-DNA20D
« on: December 27, 2013, 09:38:34 AM »
Hi all,

I am looking to build my first mod and have been looking at the Milo-DNA20D box mod.

This is what i am trying to make: http://www.howder.com/milo-dna20d.pdf

From this thread: http://www.e-cigarette-forum.com/forum/battery-mods/366666-milo-dna20d-mod-step-step-how.html

First off i can say that i have not got a clue what is what when it comes to technical stuff but ain't that bad at making things so me saying i am scared is a understatement.

I have been trailing through this forum (and what a fantastic forum it is) for information etc etc and been looking all over the web for parts, been trying to get the parts from the UK just to speed things up.

Now the tricky part and i am probably gonna embarrass myself here  :laughing2: with the items i have found, not 100% sure they are the correct items to make a fully built Milo.

Would someone be so kind to have a quick trail through the following items to see if i am on the right track before i start adding them to basket.

I have more than likely got it all wrong and have to go back to the drawing board :laughing2:

Here is what i have conjured up so far:

1 x Box case

I've just had a quick look and everything seems fine judging by milo's instructions.
The good thing about making your own is that you can change the design if you wish.
I'm in the UK and I use Perspex quite a lot, I get mine from kitronik.

Thanks :)

The only thing that is bothering me is how i will get this to fit as it is a different Atty connector to Milo's

1 x Atty connector with Ego threading

http://www.stealthvape.co.uk/electronic-cigarette-mod-parts/EGO-AUTO-UNSEALED-CONNECTOR

Also changed this:

1 x Window tinting film

http://www.ebay.co.uk/itm/WINDOW-TINT-FILM-TINTING-LIMO-ULTRA-BLACK-5-50x300CM-/281159079487?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item417663163f

too

1 x Window tinting paint

http://www.ebay.co.uk/itm/Car-Window-Tint-Spray-Auto-Lights-Body-Aerosol-Paint-Tinting-Black-Smoke-Glass-/251370853940?pt=UK_DIY_Material_Paint_Varnish_MJ&var=550322995704&hash=item3a86ded634

I've never used an ego type connector but I would assume that you would need drill the hole perfect for the connector to be push fitted and still remain solid.
The enclosure that you're using is around 2mm thick.
I use the normal connectors and I drill the enclosure bigger than the hole. I then attach the connector to a rubber and a steel washer and glue it from the inside.
I've never tried the spray paint but kitronic do different colour see through Perspex.

For the most part, you can build Milo with different parts or even a different enclosure to suit what you need.  The ego connector will be aok in Milo.  And the window tint spray is what I used before switching to tinted acrylic.

It's absolutely awesome to vape with a mod you've built yourself.  Happy modding and enjoy the venture!!

Thanks mamu, to be honest this is the one i really want to make as i love it to bits but i can only presume the above parts would need a complete overhaul, spent 2 hours yesterday just trying to find the casing and still couldn't find it :laughing2:

The battery and the tact switches that you bought for Milo are the same ones I use in Stealthy.  You will have to de-solder the leads from the batt, bend the top of the batt and tabs over to make room for it to fit in the case though.  You don't have to do that with Milo.  Or if you use the E-Fly 1200mAh, 20C lipo batt you wouldn''t have to do that as it's smaller in height and fits aok without modification.  Also, in Stealthy I'm now using smd fuses.  You might have a problem using the ego connector in Stealthy though.  I had to dremel off a bit on the underside of the 510 connector I used so that the batt will fit.

I got my inspiration for that mod from breaktru and retird.  Breaktru is the first to have made a stealth size mod using that batt box with the DNA20D and he put a 1200mAh round nano tech lipo (hobbyking.com) on one side of the batt box and the rest of the components on the other side. 

So you have options for design layout.

google "9 Volt Battery Box".  I would think a seller from ebay uk would have that batt box or maybe an electronics site in the uk.

I feel for you as this is an expensive build for you to gather all these parts from different places and with the added shipping.  Those tact switches from the uk vape vendor are really expensive.  I buy them from arrow.com here in the US.  arroweurope.com has them for £0.41, but then you'd have that shipping too.

Thanks mamu, i have been searching all morning and have decided that i like the Stealth mod more, i ain't going to try as small as that one so my box size is ( Length 75mm - Width 48mm - Height 27mm )

Plus this way i won't have to buy any tinting and Lexan clear polycarbonate and will also only need 1 lipo battery, because of this and shopping around more i have brought the price from £133.00 delivered too £115.00 delivered.

The only things i ain't 100% sure if they are correct is the Tactile switches & PTC resettable fuses 30v, 3A as i have changed supplier..also changed the finishing washer to a solid one.

Anyway here is the final list and am hoping it is correct, really looking forward to building this as i do love making things.

Perfect Romelee!

With that depth of 27mm for the case, you'll be able to fit 2x 1200mAh batts for a total of 2400mAh.  You'll really like that for longer vape time than with a single 1200mAh batt.

When working with cutouts for the case and using a dremel, just turn the speed down a bit so you don't warp or melt the plastic.  For the rectangular cutout for the DNA display, you can make it nice and tidy and square up the edges by using needle files.  Working with plastic is so much easier than working with aluminum.

With that width of 48mm, you have a few design layouts you could think about.

You can do the front and center triangle layout like with Stealthy where the DNA board rests on top of the batts, or you can do the side layout like I did with my eclipse where the batts are positioned on one side and the DNA and buttons are all positioned along the other side.

Fantastic, thought you was gonna say "Sorry all the wrong parts"  :laughing2:

With the highlighted hole is there anyway a charging light can be put there for when the USB cable is attached? if so what item would it be on this site: http://www.stealthvape.co.uk/electronic-cigarette-mod-parts



And also how is it conntected, i pressume on the USB charger not the DNA20 board.

Last but not least as i have changed the supplier for the following items i am still unsure of the specs, could you confirm they would work fine:

3 x Tactile switches
£1.52 for 5 (minimum order)
http://uk.rs-online.com/web/p/tactile-switches/0102383/

2 x PTC resettable fuses 30v, 3A
£0.38 for 10 (minimum order)
http://uk.rs-online.com/web/p/resettable-wire-ended-fuses/5176821/

p.s Deffo now gonna use 2 x 1200mAh 25C li-poly batts now that you say that they will fit, more longer lasting battery the better :D

Again many thanks for your help on this, you have helped me greatly and is much appreciated

...With the highlighted hole is there anyway a charging light can be put there for when the USB cable is attached?

And also how is it conntected, i pressume on the USB charger not the DNA20 board.

On the Evolv usb board there is a green for fully charged/red during charging LED.  If you make a small hole (1/16") next to the usb cutout on the case, that LED will shine through that hole.  You don't need to connect anything as the light from the LED will shine through that hole when the LED is lit.

Breaktru shows where he laid a short piece of fiber optic or monofilament (you can use a short piece of fishing line) across the LED on the usb board and then inserted the opposite end of that line through the hole.  What this does is make that LED light from the usb board shine through the hole nice and bright.  It's a great idea and really makes the LED light shine through the hole nice and bright.

To connect the usb charging board to the DNA board, you simply wire + from the usb board to + charging pin on the DNA board and wire - from the usb board to - charging pin on the DNA board.  Make sure you have the DNA20D datasheet printed out when you do the build as you'll need to refer to it for wiring.  The Milo tutorial also has the wiring guide and other how-to mod stuff and you should have that printed out too while doing the build.

Last but not least as i have changed the supplier for the following items i am still unsure of the specs, could you confirm they would work fine:

3 x Tactile switches
£1.52 for 5 (minimum order)
http://uk.rs-online.com/web/p/tactile-switches/0102383/

2 x PTC resettable fuses 30v, 3A
£0.38 for 10 (minimum order)
http://uk.rs-online.com/web/p/resettable-wire-ended-fuses/5176821/

The tact switch is the same as I use, except that one is a 300g force and the ones I use is a 200g force.  But other than that, it is the exact same switch.

The PTC fuses are fine - the resistance will be half when you wire it in parallel and the hold current will double and that's what you want

p.s Deffo now gonna use 2 x 1200mAh 25C li-poly batts now that you say that they will fit, more longer lasting battery the better :D

Definitely great for longer vape times between charging.

Again many thanks for your help on this, you have helped me greatly and is much appreciated

YW!

Can't wait to see your mod!!  :yes"

Hi mamu  :help:  sorry to be a pain but i have ordered all parts and just need to clear a few things up, these questions may sound silly i know.

First off, i have changed my mind on the box as the small ones turned up and i didn't like them, just didn't feel right so i have ordered this: http://www.amazon.co.uk/gp/product/B005T95KMK/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

Taken from this guide: http://www.howder.com/milo-dna20d.pdf

1st: The fuses have two legs on each, once all soldered together in parallel does it matter what leg the red wire is attached too?

2nd: You mention on the guide: De-solder and remove the on-board tactile fire button, i take it that this is not going to be of any use anymore as the new tactile button replaces this?

3rd: On your guide you mention:

C. Wire the 24g yellow wire to the down wattage control pins.
D. Wire the 24g white wire to the up wattage control pins.

(Ignoring the fire button) Judging by your picture with the wires in place the yellow is above the white so that would be top button to turn down wattage and bottom button to turn up the wattage, does it have to be this way as i would prefer the top button to up the wattage (white) and bottom button to lower the wattage (yellow)

4th: On your guide you mention:

You only need 2 legs of the 4 legs on each button. Cut the 2 legs not needed
close to the button's body. Straighten the remaining 2 legs.

Does it matter what legs of each button i use?

5th: Last but not least, i have some 3mm Dark Blue Tint Acrylic Sheet Polished Cut To Size for the face, i have to drill four screw holes and the worst part which is worrying me is making a cutout for the USB......i there any advice you can give on making a cutout to make it look very professional? i have plenty of tools (half of them i don't even know their purpose) and just got this lot for Christmas from the wife:

New box i have chosen: http://www.amazon.co.uk/gp/product/B005T95KMK/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

Do you think i will have to do this with the following cover:

Front cover i have chosen: http://www.sheetplastics.co.uk/Polished_Perspex/tint_pers_pol/dblue_tint_pol_cat/3mm_dbtint_pol

Optional: if using tinting film, because tinting plus the black transparent plastic piece will make the display too dark, I remove the black transparent piece covering the OLED. I use a craft knife and slip it under a corner of the plastic piece then slide the craft knife along the underside of the plastic piece.



So hopefully that will help me a bit (don't think tomb raider will though)

Again sorry for all the questions but i have a old saying it's better to ask questions then to guess the answers

...First off, i have changed my mind on the box as the small ones turned up and i didn't like them, just didn't feel right so i have ordered this: http://www.amazon.co.uk/gp/product/B005T95KMK/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

That's a rather large enclosure height and width wise compared to the Hammond 1590ABK or the plastic one you had ordered, but is certainly doable.  With that width and height, you'd be able to fit bigger batts with more mAh and have even longer vape times.

1st: The fuses have two legs on each, once all soldered together in parallel does it matter what leg the red wire is attached too?

Fuses have no polarity, so it doesn't matter.

2nd: You mention on the guide: De-solder and remove the on-board tactile fire button, i take it that this is not going to be of any use anymore as the new tactile button replaces this?

Correct - the onboard fire button, as well as the onboard up/down watts buttons are not used.

Removing the onboard fire button is to reduce the height so everything fits inside the case.  I also remove it even if I do have the space as a caution cuz I don't want it accidentally pressed from the inside.  With some of my mods space is at a premium - batts, switches, electronics, etc are packed in so that one component is butted against another or sits on top another.  I don't want anything to accidentally press that button so I always remove it.

What I've been doing this last year to remove that fire button is use a small nipper to cut the button's leads off the board.  I carefully insert the nipper just under the edge of the button and into one of the leads soldered closest to the edge of the board and snip that lead off.  Then I do the same for the other lead soldered closest to the edge of the board.  After those 2 leads are removed, I gently rock the button back and forth til the other 2 leads break away.  You have to be careful when doing this, and you may lose the 2 traces that run underneath that button, but the traces under the button are only for the onboard button so no worries if you do lose a trace.

If you're not comfortable doing this, don't do it.  I've done it a kazillion times now and have gotten it down pat where I insert the nippers at a high angle underneath the edge of the button and into the lead and just snip the lead and don't lose the traces.  But like I said, if you lose the traces, or even the pads, not a big deal as they're not being used.

3rd: On your guide you mention:

C. Wire the 24g yellow wire to the down wattage control pins.
D. Wire the 24g white wire to the up wattage control pins.

(Ignoring the fire button) Judging by your picture with the wires in place the yellow is above the white so that would be top button to turn down wattage and bottom button to turn up the wattage, does it have to be this way as i would prefer the top button to up the wattage (white) and bottom button to lower the wattage (yellow)

Yeah well what I did with my 1st Milo when I wrote that tute was backwards - I blame it on the leftie in me.   :laughing:  Since then I wire the correct way with the up watts button on top and the down watts button on bottom.

With these builds you have the option to do it any way you like.  And it's funny, but I've been waiting for just this question for about a year now and you're the first to mention it after all this time.  I'm sure people have wondered about it though lol.

4th: On your guide you mention:

You only need 2 legs of the 4 legs on each button. Cut the 2 legs not needed
close to the button's body. Straighten the remaining 2 legs.

Does it matter what legs of each button i use?

Yes, it does matter - if you cut off the wrong 2 leads the button will be unusable. 

If not sure which 2 leads to cut off, check continuity with your multimeter.  Place one probe on one lead, then the other probe on another lead - press the button.  If you hear a beep and get a reading those 2 leads are connected and you can wire to those 2 leads.  If you don't hear a beep or get a reading when pressing the button, then those 2 leads are not connected and cannot be used together.

A quick way though, is that with that tact button, the 2 leads on one side are connected and the 2 leads on the other side are connected.  So if you cut off the 2 leads on one side, you'll use the 2 leads on the other side for wiring.

5th: Last but not least, i have some 3mm Dark Blue Tint Acrylic Sheet Polished Cut To Size for the face, i have to drill four screw holes and the worst part which is worrying me is making a cutout for the USB......i there any advice you can give on making a cutout to make it look very professional?

I have a dremel bit set: Durable 3mm Shank 3mm CED Tungsten Carbide Cutter Rotary File Bur Burr 20Pcs

If you look at the pic, the tapered tip the 9th from the right is the one I use to cut the usb cutout.  I dremel to just an unch around the edges of the cutout, then use a round needle file to tidy up the hole and shape it to how I want.

For the size and shape to cut the the micro usb cutout, you can google it and look at images and then print it and use that as a guide.

Here's the template I use for the Milo door (your template height and width will be bigger since you're not using the Milo case).  I use double sided tape to adhere the template to the piece of acrylic, then cut and shape the outer edges and round the corners with a dremel heavy duty cutting wheel.  Then using 320 grit sandpaper, I sand the edges and corners nice and smooth.

I tried to copy this 1:1, but it looks bigger than the actual Milo door template... but it gives you an idea of how I do it...

The other reason i chose that box was because it is my first time build so i also thought better for me to have more space to work with to get used to how things work, didn't want to dive into the deep end.

Yes, it does matter - if you cut off the wrong 2 leads the button will be unusable.

So i cannot just simply for instance just cut off lets say the top two legs and use just the bottom two legs of each tactile switch.

Ignore my post about the tactile switches, all sorted, went out and bought a new multimeter as my other one decided to die.

All switches when the button is pressed beeped on the multimeter using this format:

mamu, last question i promise (i think)

I am having problems with the company who i bought these from:

2 x 1200mAh 25C li-poly batts (Length 60mm - Width 20mm - Depth 10mm) from here  http://reflexshop.co.uk/index.php?main_page=product_info&products_id=51773

They have took my money but i ain't had any confirmation of order, been emailing them for about 5 days now and still no answer >:(

So i think i will have to get some from here: http://www.hobbyking.co.uk/hobbyking/store/index.asp

I am totally useless when it comes to batteries, would you be so kind to choose one for me that will work with the fuses etc etc that i bought above and will fit my new box from here: http://www.amazon.co.uk/gp/product/B005T95KMK/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

Preferably in stock in the UK

Apart from that i think i am good to go, all other parts will be with me tomorrow.

Many thanks

Jason

If you take a look at the picture I show in the Milo tute, you'll see that you'll need to wire the leads on the left side and cut the leads off that are on the right side.

I'm not sure if you're familiar with working with lipoly batts, so I looked for 1S batts and here's the options for the case you've chosen:

You may be able to fit 2 of these 2200mAh lipoly batts if you bend the tabs over (the height is too long with the tabs extended): http://www.hobbyking.co.uk/hobbyking/store/__34562__Turnigy_2200mAh_1S_20C_Lipoly_Single_Cell_UK_Warehouse_.html

2 of these 1000mAh batts will fit, maybe 3: http://www.hobbyking.co.uk/hobbyking/store/__34561__Turnigy_1000mAh_1S_20C_Lipoly_Single_Cell_UK_Warehouse_.html

3 or 4 of these 1000mAh round nano tech batts will fit: http://www.hobbyking.co.uk/hobbyking/store/__37564__Turnigy_nano_tech_1000mah_1S_15C_Round_Lipo_UK_Warehouse_.html

3 of these 1200mAh round nano tech batts will fit: http://www.hobbyking.co.uk/hobbyking/store/__40130__Turnigy_nano_tech_1200mah_1S_15C_Round_Lipo_UK_Warehouse_.html

The batts recommended for Milo don't need any wiring to the tabs or modification - the batts listed above you'll need to wire directly to the tabs.

When working with lipoly batts, be very very careful that you don't short the batt (explosion and fire hazard), rip or puncture the foil (explosion and fire hazard), and when all the wiring is done completely cover the tabs with electrical or Kapton tape.

It's much simpler to just use the leads on one side and have the wires going in the same direction.  Less brain work that way.  :laughing:

Is there any word/picture guide you know of, of how to wire them up?

Never seen batteries like them, hence me not knowing much about the battery side of things :(

The two top pieces on each battery covered with yellow Kapton tape are the connection tabs - When you're working with a li-poly as Mamu said you need to be careful not to short it out so take the first battery - The tabs will be marked + & -  Remove the Kapton tape from one tab - solder on a wire (you don't have to use different colored wire but i would just to reduce sods law) let it cool down and cover and cover the solder joint and tab in either electrical tape or Kapton tape (You need to cover all of the exposed wire solder joint and tab with this) . Once you have it covered do the same to the second battery tab .. When you have done both batteries then you have it pretty much like Milo - Strip the positives on both batteries . join and wrap them as per Mamu's pic and then do the negatives (and don't forget the fuses lol)

Be careful not to leave a + and - unwrapped at the same this will reduce your chance of having any shorts going on - You can actually solder the tabs together and then add a single wire to each tab but it's a lot more Faff if you get  a dead cell to remove things that way imo

Here's a vid with a pack being taken apart - Bear in mind though that this is done in series + to - but at least you can see the tabs on here - As you are only using two bats you don't need to worry about soldering the tabs together over a board but it does at least give you some general rules in working with Lipoly (even if he doesn't follow his own advice lol)

I would recommend against disassembling packs for individual cells.  You can get individual cells from HobbyKing for really cheap so there's no reason to do it in terms of expense.

There's a couple problems with disassembling packs.  For one, you're subjecting the cells to the heat of soldering three times, first for the original installation, second for removal, and third for remounting.  The tabs can take an amount of heat, but you risk damaging the cell every time you solder one.  Also, the tabs have been trimmed which can be a problem for remounting.  It makes it physically more difficult to mount the cell and increases heat exposure since the tabs have to be soldered closer.

If you have one of those archaic soldering irons like the one in the video, throw it away.  They're not even good for soldering wires.  They're far too hot for soldering any kind of electronics, especially LiPo cells.  You should be using a decent quality soldering station with an adjustable temperature.  There is no exception to that.  If you don't have an adjustable soldering station, you 're going to have to buy one.  They're not particularly expensive so it shouldn't be a problem.  I recommend the Hakko FX888D.  It's one of the more inexpensive stations and the quality is very good.

Yeah i meant to add the deconstruction video is only there so you can see what the tabs look like and the precautionary measures you should take when working with li-po bats - There's simply no point buying packs to rip them apart when you are doing single cells but in parallel - It's much easier and less destructive to buy single cells that you linked and wiring them yourself

Sounds fair.  I've seen people do that for building mods and I wanted to point out there's really no reason to and it's not a particularly good idea.  Also that ridiculous soldering iron, wanted to make a point of that mainly.

Those irons were designed for electronics of the 1950s that had very large circuit board pads and large heavy terminals on tube sockets.  You need a lot of heat to solder that stuff.  They were fine for that, but they became obsolete as soon as electronics went to solid state.  Modern electronics require precise temperature control to avoid damage from overheating. 

For some reason people think those industrial age soldering irons are still relevant.  I think you can even still find them for sale.  Talk about using the wrong tools, can't think of a better example.

That iron you an find at harbor freight and auto stores I saw one last week at Oreilly's thought it was a good iron too it had all kinds of attachments like a plastic cutter head foam etc.   Woot grand info again this forum rocks..

When you say it gets hot OMG..

I wouldn't touch that without a complete chemisty lab setup - The details on their site are

Product's information
Product name:99.8%,998mg/ml pure nicotine
Extract part:natural tobacco leaf
Appearance:colorless to shallow yellow oily liquid

You have bought 998mg nicotine which like i said i would not touch without full lab equipment - Respirator , heavy gloves, eyewear and extraction fans - The full works - I would touch it even less without full nicotine titration kits to be sure of your actual strength of nicotine.

Batteries have been dispatched :D

Quick question, them + & - tabs, when the tape has been taken off do the tabs have solder already on them? so it's just a case of soldering the wire too them.

If they don't have solder already on them do i need to put some flux on the tabs before putting some solder on the tabs?

Don't know if this soldering iron is gonna work though, i have the following (don't laugh...hehe)

http://www.rapidonline.com/Tools-Equipment/Draper-60w-230v-Soldering-Iron-91-4099/?source=googleps&utm_source=googleps&gclid=COXMyMzG4rsCFUr4wgodiiYA_g

and this one:

http://www.amazon.co.uk/Dremel-F0132200JA-VersaFlame/dp/B001DH7SP4/ref=sr_1_1?ie=UTF8&qid=1388770889&sr=8-1&keywords=dremel+blowtorch

If they ain't no good any thoughts on one that will, i have looked at the Hakko FX888D but that is out of my price range atm.

Cheers again

To solder the tabs, you need to use some Scotchbrite or similar on them to get the surface as clean as possible.  Then apply rosin flux liberally.  Use 60/40 or 63/37 rosin core solder.  Avoid exposing the tabs to the heat of soldering for extended lengths of time.

60 Watts is way too hot.  Even a 25 Watt pencil is too hot.  Those are typcially 750F and you don't want to go over 600F with the tabs.  If you insist on spending as little as possible on an iron, use a 25 watt pencil like this.  Though, I strongly recommend you spend the money for a proper soldering station.  The Hakko one I mentioned can be found for under $100 in the US, but I see you're in the UK so I can't help you with vendors. 

Post #33, was off the wall.  I see people talking about getting pure nicotine every now and then, the Chinese will sell you anything.  That stuff is way too dangerous to handle.  One of these days someone is going to hurt themselves.

Post #33, was off the wall.  I see people talking about getting pure nicotine every now and then, the Chinese will sell you anything.  That stuff is way too dangerous to handle.  One of these days someone is going to hurt themselves.


I'm thinking that its a spammer. Especially looking at the members email address which no one else can see.
I am about to delete it unless    clueless vapor can convince me that he's legit.

Sorry CraigHB i linked the wrong solder iron, got this one: http://www.amazon.co.uk/Draper-71416-25-Watt-Soldering-Iron/dp/B0001KA1Q2 and the other one i linked.

Only info i have on the dremel soldering is that it it : 550°C (soldering tip)

Not sure if the tip will be good though and will be good enough for the rest of the setup.

Aint got a clue what solder has been supplied with the Draper solder and the Dremel solder but found this: http://www.ebay.co.uk/itm/1-0mm-Soldering-Wire-Solder-Iron-Dispenser-Tube-60-40-Tin-Resin-Flux-Rosin-Core-/400601869529?pt=UK_Home_Garden_PowerTools_SM&hash=item5d45bb6cd9

One thing that is confusing me is, once all fitted/wired and the mod  is ready do i just charge the mod as usual or are the batteries already charged, it's just that i am reading all bad stories on google about parallel lipo batteries etc etc and am getting quite worried.....i think i am looking into it too much and am worrying myself tbh

The 25 Watt iron you linked to should be able to do the job.  Just be a little more careful with heat exposure since it's going to be somewhat hotter than ideal.  Make sure the tip is cleaned, tinned, and shiny before applying it to the tab.  A clean tip maximizes heat transfer reducing soldering times and heat exposure for the cell.

LiPos are a bit more hazardous than the round cells in that the tabs are readily exposed to short circuits.  I've accidentally done that a few times myself.  It startles the hell out of you when it happens, but they're not like TNT, they don't explode instantly when mishandled.  They can actually take a good amount of abuse.  I've done some ugly things to the cell I keep on my workbench for testing with overloads, overdischarge, and short circuits and have not had one catch on fire from that. 

LiPos are are vulnerable to physical damage since they are only encased in thick foil compared to the hard sheet metal tube of the round cells.  A puncture will light one up for sure.  You need to be more careful with them physically.

For any Li-Ion including LiPos you have to take care when using them in parallel.  If there's a big differential in charge level when initially connecting them, large equalization currents can occur that can cause overheating and possibly fire.  Just measure each cell prior to making the initial connection to make sure voltage is matched within a few hundredths of a Volt.  Once they are permanently connected, they behave as one cell and there is no longer any worry.

Cells normally come from the maker with a charge of 3.8 Volts.  This is the ideal charge level for storage (40%).  All of the new cells I've received have been very close to that so likely if you connect them before doing anything with them, they will be matched in terms of charge level.  You should still check them before connecting them.

Oh, in terms of solder and flux, any 60/40 or 63/37 rosin core solder and any rosin flux should be fine.  There are various types of rosin flux, like water base or "no clean", but I prefer the activated RMA type.  The activated RMA type works really well, but it has to be cleaned off with pure ispropyl alcohol after soldering is complete.

Delete away, just really odd a spammer would make a post like that, and also that it's about as OT as you can get for the current topic.  There's no sense in it.  Amazing the noise that pops up on the net sometimes.

I agree and if you do please feel free to delete any of my replies to help keep the thread reading on topic - I thought it seemed a little fishy but put the posting in the wrong place being with a new member but you can never tell so thought i should at least give some general safety advice

I myself found it a bit strange of posting about nic base on this thread but thought he/she was a bit lost but now looking at the nic base  freaked_out:

The 999 pure is an amazing vape it show you the face of GOD. :wallbash:  lol

I switched to Kester solder with Craig's recommend of 63/37 that solder is leagues beyond any solder I have used. 
It will tact anything by itself put some flux with it and whoa thats welded ... :thumbsup:

I was using IDK whats in this solder from china, said it was toxic safe and low melting point -- it was horrible...  At work we use a torch and rod to solder lugs on, smallest wire we work with is #10, I knew notta about electronics solder then, now woot.

I've come across that Chinese stuff before.  I don't know what the hell it is, but it melts like paste and hardens to an ugly dull finish.  Joints come out shiney and clean looking with the 63/37 which I like much better than 60/40.  You wouldn't think 3% either way would make much difference, but it does. 

The thing with leaded solder is that just about all makers have implemented the ROHS standard that eliminates the use of it.  I'm hoping that tin/lead solder does not become hard to get at some point.  It really is much better than anything else.  The lead free stuff doesn't work nearly as well.

Got myself some of this: http://www.ebay.co.uk/itm/370880533175?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Atleast i will know what it is as the other solder does not indicate what it is.

Looks like the good stuff, 63/37, rosin core, 1mm.  Should do the job nicely.

It doesn't say, but the rosin is probably the standard activated type so you'll need to clean it off with isoproyl alcohol when done soldering.  You can use the higher purity rubbing alcohol from the drug store, something like 90% will do.  I normally buy the technical grade stuff from MG Chemicals which is like 99.5% pure, but I've used the 90% rubbing alcohol from the drugstore before and it works well enough.

lol @ the thread spammer.  It's like wut?  :laughing:

It's good to have a healthy concern about what you're going to be faced with when working with lipoly batts, Romelee.

Good info and advice here from warlord and Craig.

I remember my first time - all the cautions and concerns and I was freakin a bit.  After a few times of working with them, you're not as nervous, but still always cautious.

Another option with the size of enclosure you have, you could easily fit a dual 18650 batt holder and use dual parallel 18650 batts.
