I agree with Ryland. You'll want to use more than 48V to get around. If you double the voltage to 96V (which is most likely not a problem for the motor), you also double the rpm of the motor (assuming its a series wound motor), so you can get 3200 rpm out of it and 18 kW @ 186A. This will reduce the amp draw for the same power and really help out your battery life.

What kind of range were you looking for?
