So I got this broken safety light from work. It has all kinds of jumbo LEDs inside that flash in a safety pattern. Somehow somebody took out some serious fury on it. The outer case was ransacked. The PCB was demolished. But the 1s 1300mAh lipo was in tact. I salvaged it and brought it home. When I checked the voltage it read millivolts. I guess some water must have gotten to the board and caused the cell to completely discharge. So I read online where you can set the charger to NiMh and charge it at 100mA to 3v then shut it off and charge normally. Initially the cell would not do anything on the charger but after charging on NiMh mode, the LiPo mode now works. So I set the charger to 1.3A rate and away it goes! So far it's at 42 minutes and has charged 685mA of current into the battery. It's at .4A charge rate currently and everything looks good. The cell shows no signs of puffing and isn't hot. Sure be nice to get a free lipo...for what it's worth...
