my balancer stops at 85% ?

Are any of the cells far enough out of balance that a high cell exceeds 4.2v before the others? Try balancing without charging until each of the cells are equal, then start the charge.

Yeah, if you are going by the percent meter, wallot is right; that is just an estimate. There is no way any device can know the accurate charge level solely by voltage. The best it can do is estimate because lipos do not have a linear discharge curve.


About your other charger. Does it require a 12v DC input? If so, is the power supply strong enough to maintain ~12v and the current required?
