Why not try SMC lipo's, if damaged in this way they do offer a 2 year damage protection. You send them a copy of the receipt, picture of the lipo and then if approved they will sell you a new one at a 60 percent discount.

I think that is pretty darn fair and I really do not see anyone else doing that.

On another note I would just get rid of that lipo. God forbid it catches fire in your buggy your out more then just a lipo.
