Two BC168 chargers on 12S pack?

[Haohmaru]

Will two BC168 chargers read voltages accurately with packs smaller than 12s? I was hoping to implement the same charging setup of 2 PSUs & 2 BC168s for my 9s packs?

I think you will have the same problem as I did if you share a sense/balance lead between the two chargers.

This is one of those situations where separate wires to the packs solves the problem. If your 9S pack is a 4S and a 5S pack in series, with separate balancing wires, then it should work fine. No sharing wires between balance connectors!
