My brother brought his 3 cell, 1100 mAh lipo down to about 6 volts. I thought it was trash so I just left it alone, a few weeks later, I decided to try and recharge it.. charged it as a 2 cell lipo at about .5 amps and it only took a few minutes before it was back up into normal 3 cell range. I have used the pack for about 10 cycles since, no puffing, no problems.
