The bottom line (for Codi) is that the i-charger just cannot balance an imbalanced pack without charging it. Even if charging it then in order to deal with such a bad imbalance then the rate needs to be set very low(slow)
One of my complaints about it is that it cannot just "balance" , but apparently that new bigger dual one can.
A tool to consider is an old stand-alone "balancer" I like the digital ones , but they're dog slow. I still like to abide by this rule when hooking series cells/packs together: All cells must require the same amount of capacity. Even though there are boards/connectors,ect. available to hook them up, to force any charger/balancer to deal with this is really asking it to do something it wasn't designed to do.
