5 cell battery/1 cell peaking before others. HELP

[lincpimp]

Charge the other cells separately thru the balancer port until they are all filled. Then run the pack and see how far out of balance it goes during a run, pull 2000mah out of it, not a full run but enough to see what is up.

2 amp max thru the balancer wires, about all they can handle given the gauge.

It once took 36hrs or so for me to balance a maxamps 10000mah pack...

This is why I like the little 25 dollar HC charger that charges all of the cells individually. Great for older packs that go out of balance but still have some life in them.
