I just remembered there's a left-over controller from the forklift: it's a GE EV-1 (not the car) SCR controller. I understand they're less efficient than PWM, and potentially harder on the batteries, which is why we didn't use it in the car.

But others do - you can probably find a dozen cars & trucks on the EV Album using the same one. If I were you, I'd also seriously consider a simple, 100% efficient, 2-speed 24/48v contactor controller. (Or 3 speed with a fat resistor step: 24v+resistor/24v/48v. You don't really need infinite speed control on a lawn tractor.

But you can have the EV-1 for shipping cost, if you want it.
