Lipo Problems UPDATE

I have a Turnigy 1700mAh 7.4v battery. I've been running it in an RC18T with a Mamba Micro Pro. One day I went to use it and it was dead. I tried charging it and the charger came up with "CONNECTION BREAK." I checked the voltage. Absolutely none. I tried charging in NiMh mode: same message. Is this a loose wire or something? I don't think it's deep discharge since there's no voltage at all. Help!

I found the problem. The negative tab is ripped in two. Probably got pulled at some point. So now what? Any tips (Pun there) on how to solder it?

EDIT: Also checked the voltage of each cell. One is at 0.8V and the other is at 1.2V for a total of 2 volts :eek: Looks like a deep discharge as well, probably related.
Should I just scrap it?

That's what I'd recommend at this point.

Lol, Ok. :P If the only problem was the broken tab, or the only problem was the discharge, I might try to save it. But both? Not worth the $15.
