Last night I was charging a 2S A123 pack. Due to operator error (don't ask, I'm not interested in enduring an iquisition regarding my charging methods) I let the pack get to almost 12V at about 3-4A. The end of one cell blew out. The pack flew a couple of feet and landed on the floor. There was no smoke or fire just a bunch of black power and copper foil.
Black power eh?
Must be a gang-cell (a bit like a terrorist cell really) :-)
I think it might be time to squeeze all that shirt back in there, tape it up and put it on eBay as an (ab)"used A123 battery" :-)
