wow...so I have I think one of these coming on my way...since the 10 amp one is not available?no pot and no caps...how do I adjust?......thanks,...do you still sell them?
The mod in the OP (1st post) is not the PTR08060W. The video mod above in Reply #45 is.The PTR08060W is wired exactly like the PTR08100W and the parts are the same. See the "Variable Voltage Evercool Copper Mod" Topic for wiring details. Caps, resistor and pot is required as shown
I am wanting to build this mod ( awesome work breaktru) I have all the parts ordered just patiently waiting (NOT!) for them to get here..lolOne question. I want to put a DP in it and I could only find the DS1809-10. What ohm resistor would I use on the VO line to keep it between 3.7 & 6.2? I have seen posts here with 4.7k,220 & 10k. I guess I am over thinking it because I know it right in front of me. lolThe Dp I want to use is like this one http://breaktru.com/smf/index.php?action=dlattach;topic=177.0;attach=460;imageI am using the PTR08060W instead of the 8100TIA for any help you can offer.
I posted that wrong it's a DS1809-100As for the basic wiring I was gonna follow this one http://breaktru.com/smf/index.php?action=dlattach;topic=170.0;attach=495;image
Ok I reread all the DP threads. I see where I went wrong thinking (or not thinking...lol) that was right. I have linear pots here so I can use those w/ the 8060's . I'm gonna go with the 8050 for the DP mod. Now after reading more this morning I am interested in using tach/touch switches in my mods (I love your bullet switches) Would the STD30PF03LT4 MOSFET be a good choice for both uses ?
Is it ok (safe) to use a USB charger in this case with 2 of these https://www.fasttech.com/products/1066606run in parallel? I would like to do it but don't want to run into safety issues. Sorry for all the questions but its better safe then sorry.
Thanks Breaktru. I think I'll be ordering some better battery's for this. I ordered those before I started this project & I can still use them in my old ego-t so they won't go to waste...lol
There are some not so obvious hazards when using unprotected Li-Ion batteries both in serial and parallel.For parallel cells, you have to be careful that voltage betwen them is pretty much exactly the same upon initial connection or you could get heavy equalization currents. If the mismatch is great enough, it can cause a battery fire. At the minimum, it can damage the cells. Though, once the cells are connected and equalized they behave as one cell and there's no longer any concern.Another hazard with parallel cells is if you inadvertently place one into a battery holder backwards. It's actually pretty easy to do since you really have to look to identify positive and negative on the flat tops. A reversed cell creates a radical short between the two, each working to push current into the other. That has to be about the worst thing you could do to a pair of Li-Ion cells.With parallel cells, I recommend using a USB charger which eliminates the need to remove them for charging. Eliminating the need to remove the cells eliminates the above hazards.For series cells, one cell almost always discharges faster than the other. That's just due to normal tolerances in production. The risk there is that if the pack is discharged deeply, one of the cells could drop below minimum voltage tolerance. It damages Li-Ion cells if they are discharged too deeply.All of these hazards can be avoided with a protected cell, but the problem there is smaller cells may run up against their drain limit. For example, two protected 14500s in parallel would have a continuous drain limit of only 3 Amps. Each cell's protection would probably trip around 2 Amps so that would be 4 Amps maximum for the pack. That's probably enough amperage for most vapers, but if you're using unusually low resistance or unusually high power, your pack could cut out on you. For larger cells, it's not an issue. A protected 18650 can usually deliver around 6 Amps. Two in parallel can deliver up to 12 Amps.The highest quality cells are the name brand Japanese ones like Sony, Panasonic, Samsung, etc. The best Chinese cells are the AW brand. For an inexpensive Chinese battery, the eFest brand seems to meet ratings and deliver acceptable performance in benchmark testing. The "fire" brands are some of the poorest performers so I would have recommended you not buy them, but since you already did, just use them at Breaktru said.
