I'm new to shopping for scooter controllers. I've got a BladeZ XTR Street. It has a 24V brushed motor (just two power leads to the motor, that can't be brushless, right?) fused for 30A (rated for 20A, I think) and 2x12V SLA batteries. The throttle goes from approx 9k (0%) to 5k (100%), but I could probably adjust or reverse that with some judicious pot and resistor substitution. The power switch is "soft" (connects to the controller, not inline with the batteries).
At a minimum, I'm looking for a throttle controller. I can put a power switch inline with the batteries and wire up the charger separately if I have to. I'd prefer to find a controller that can handle the soft power switch and charging as well, if possible. Can anyone recommend a controller that could work for me for this project?
PS: Price is a factor. I can get the exact replacement controller for $120, but I'd prefer to find something significantly cheaper.
