Go for the iCharger if you are doing RC Charger, dont skimp on the charging amps. Like the $20 iMax 6S charger takes a long time.

You might have to put two in series to get your voltage which you can adjust, but you can not adjust the amps. If you have a 10Ah pack, best to get a 10A unit. Series you add the voltage and the current stays the same.
