So I took apart my 3S2P 8K pack and made it into a 2S2P pack to match the other 2s2p 8K pack I had to make my 5S pack (2s+3s.)

It was a pain to take apart, as all the packs had double sided tape holding them together and I had to coax them apart. It was pulling the silver wrapper so hard on a couple I used a blade to gently score the tape so it would peel apart. Unfortunately I did get a tear in two of the cells.

It smelled a bit odd, so its what made me look, and that's when I saw one tear. The other one got cut as well as careful as I was. I sealed them back up, and did not puncture the batt, as I could see an inner lining, but does anyone know what would happen when the outer wrapper gets torn? Smelled liek hydrogen or something. I'm going to dispose of the cells regardless, I don't need them and its not worth the risk using them, but I would like to know what would happen if they are used like that.

Small rocks get under the cells/batt tray and scratch at the lining. If it ever did tear it so I couldn't see it, is that highly dangerous? I can't think it would be so much so as many ise lipos in cars and these things will just happen, but then again...:032:

Otherwise pack went together ok. Now I have 1 4S 8K pack (2*2s), which is good enough for me. I'll be looking at A123s down the line, but I'll get by on one batt for now.
