Battery Charger Protection - Explosion Proof
« on: March 09, 2012, 10:36:03 PM »
Is this explosion proof or adding shrap metal to the bomb?  :Thinking:

I dug up this old thin and have been using it for a couple of months. Hope I don't kill myself  :facepalm:

Hehe, looks like a pressure cooker.

I charge my wife's eGo batts in the dining room on a big glass table with nothing around that can burn.  Hopefully, I can successfully build a VV mod for her that's small enough so I can get rid of all those horrible eGos.  I hate those things.  They wear out in like two seconds, they fail a lot, and they explode on the charger a lot.  So far, I've heard four accounts of an eGo exploding on the charger.

I don't have to worry about my own mods.  They have fail safe redundancy on the protection systems.  I use a full featured charger controller (Microchip MCP73833) with both cell temperature and time-out safeties.  I also have a 600W TVS diode (Littelfuse SMBJ5.0A) at the USB receptacle on the mod to protect the charger controller from power surges that could be picked up by the USB wall wart.  I have three over-current protection systems.  There's a PTC fuse, a voltage detector, and a current sensor that can all shut down output in the event of a fault.  My feeling is there's no such thing as too many safeties with a Li-Ion cell.

Should prevent a possible fire I imagine.
Good idea. Have to see if I can find something like that.

Before I got out the Marine Corps I snagged a few Ammo cans. I used one for a lipo charger for my R/C batteries.  I figured it if its good for ammo should be good for lipos  :rockin smiley:. I too made some vent holes. I'll take some pics when I get home. It looks like an alqueda production tho =\

I have a few ammo cans as well. 5.56 cal, 7.62 cal and .50 cal. Mine are full of reloaded ammo.
