question, dropped my voltage on my lipos abit low, now my charger (core rc) refuses to charge them and try bring the volages back up, they are a 4s 5000mah,whats the best way to bring the voltages back up??
Nimh charge it at .5a until, the voltage is high enough to lipo charge, do it outside if possible and keep a very close eye on the pack as you do it. I've done it a few time myself and never had a issue
