Default Lipo Question

A neighbor of mine asked me to help him out with his battery/charger which is not working. His charger refuses to charge his battery. I noticed that when he gave me his stuff he did not have any sort of balancer set up. When I tried charging his battery on my Hyperion 0606i with the balancer plugged in, it displayed an error message that the voltage is too low and would not begin to charge.

Is there a way to charge his battery or is it toast from never being balanced? There is no visible evidence of damage to the battery.

Sounds like he discharged it too much. If you have a volt meter, try to get the voltage of each cell using the balancing plug. If both are below 3.0V connect the pack to a standard Ni-CD/Ni-MH charger for just a few minutes. This should allow you to get the individual cell voltages up above the 3.0v mark. Once the pack is above 3v/cell you should be able to start charging it as normal.

Be sure to keep a close eye on the pack through it's next few cycles. Of course depending on the quality of the pack, and how badly it was over dis-charged, this may or may not work.

Just be very careful with it. It would also pay to have either a lipo sack or other fireproof container to put the battery in throughout this process.

Good luck. Keep us posted.
