I forgot to unplug a 2200 mah, 11.1 v battery on Saturday. I've done this a couple of times, so I figured I'd search the interweb to see if anyone had info on recovering these batteries. Sure enough, there is a way. I set my charger to NIMH battery and charged my LiPo until it hit 9v. Then put it on LiPo balance and it works like a charm!
Obviously, this may not be safe and you do so at your own risk, but worked for me.
