Last night I was looking at a smart charger I have laying around. I opened her up n was surprised how much electronics there are in this thing.. very impressive system.

It's a 4 cell meant for C size NiMh batteries that does em as 2/pair, not 4 in series. I also noticed it doesn't have any temp sensors in the compartment, it must have a different feedback system based on load n voltage. Well my batteries are arranged as 2/pair so I'm going to hot wire the outputs to the original charger's holder where my cube fits (disconnect the internal jumper) and do em like that.
