This is the charger that I bought two years ago, when I decided that I would be staying with the hobby.

You need to make adapters for your battery, but its a great charger that will do up to 10 cell Nimh. It also does NiCd (does anyone still use them?) and LiPo. The instructions are pretty poor, but you can always call Horizon Hobby tech for help.
