how to fix or repair a dead lipo battery

• Connect the main plug of your LiPo battery to your NiMH charger and start charging at the lowest current possible. Typically this is 0.1A. ...
• After a minute or two your battery should recover to about 3.3 volts per cell. ...
• When the total voltage is equal to about 3.3 volts per cell you can move the battery over to your LiPo balance charger and balance charge at 0.5C rating. ...
• Once the balance charge has completed balancing you should have a fully recovered LiPo battery.

How to revive a dead LiPo cell?

Here’s how you can revive your dead lipo cell, using a charger that can charge lead-acid batteries (Pb) and a battery checker. Sometimes it isn’t safe to try to revive a dead lipo cell. If the cell is at 0V, it will not hold any charge if you try to revive it, and the voltage of the cell will spike and the battery might burst into flames.

What happens when you remove a cell from a LiPo battery?
