Default I killed my lipo?

My hand slipped while soldering and I poked a hole in the blue film on my lipo batts. The tip beeeaaarrrlly touched the silver surface, but it's not charging anymore so I'm assuming I killed it.

Are lipo that sensitive to heat?

i would just ditch them. I know they can be sensitive but I would never take a chance with them. You might not have touched it to badly but it is damaged in a way.

I think you might have killed em...don't want to seem like a jerk or nothing but did the lipos work prior?

sorry thats all i can really help with

Do you have a voltmeter? check and see their voltage. They have a very quick discharge rate but just a brief moment shouldnt have killed it unless they were already really low charge.

I know that I was able to steer with it before I poked it, but I don't know if the forward/back worked since I was replacing a fet. But I rewired the steering right now and that doesn't even work now so I think it's safe to say that it's dead :/

no voltmeter :/


Addition: also, I hadn't let it charge for months....maybe half a year, I might have let the voltage run too low.

I know this might sound crazy but one time I left my xmod on and the lithium batteries drained down to ZERO volts, however, the atomicmods charger has a special mode it goes into that can sometimes save the batteries by trickle charging. Believe it or not those batteries I left on charged up after about 5 horus on that atomicmods charger.

Sounds pretty crazy, yeah, but it's definitely worth a try. It'll save me 20-30 bucks if it works. Bit scared though with all those warnings for lipo batts on the atomicmods site. Great way to make people paranoid. lol.
Better safe than sorry I guess.

Eh, I'm not scared! If you want you can mail me the lithium batteries and I'll try to charge them for you on my charger. I'm a verified service provider on this site so you know I can be trusted

just barely touching the tip to the battery case wouldnt be anything i would be scared of. they can be sensitive, but not that sensitive. check them with a voltmeter see what they show. this will let you know if its something with the batteries, a solder joint, something with the xmod or what.

lol, I found the problem.
I was charging it right now and I lifted it up to feel if it was getting hot or anything, and then the wire I had used to lengthen the stock wire popped off. Noob soldering on my part was the problem. lol

...well, at least I hope that was the only problem. I'll find out after I re-solder it.

Addition: Yeah, that was the problem. I re-soldered it, and finally got to use my shrink tubing that's been laying around for a while. It's charging now
I'd better practice my soldering skills... lol.

Thanks for the help guys

Great I'm real glad, now invest the money you would have had to use to replace the lithium on a voltmeter!
