5 cell battery/1 cell peaking before others. HELP

[BrianG]

First of all, the balancer in the 720 balances at a MAX of 300mA. So, let's say you need to "bleed off" 2000mAh, it will take at least 6.5 hours, and that's assuming the max rate of 300mA.

A stand-alone balancer won't speed things up that much because the fastest I've seen (Thunderpower TP-210) works at 450mAh IIRC. Your best bet is to use what you have and just let it take as long as it takes.

Second, I would be curious as to why it got so far out of balance? Did you balance the pack before, or is this the first time? If you've been balancing all along, you may have an issue.

BTW: Welcome to the forums!
