So I bought this charger and I must say for the price it is pretty good. I am running a B6D and a 17.5 motor, and SMC batteries. I run at a small high traction track and I must say, this charger delivers a well powered battery. It charges at ten amps max and is touchscreen. It has a port for balancing as well. I know ten amps don't seem like much, but not all of us can utilize that just little edge when you charge @ 40 amps or more.
