Under Voltage Battery Protection: When the battery pack falls below a specific Voltage the controller turns the motor off preventing over discharging of the battery pack which extends the battery packs lifespan. (The cutoff value is approximately 20.5 Volts ± 1.0 Volts)
Motor Cut-Off During Braking: When the brakes are engaged the brake switch signals the controller to turn off the motor. The motor turns on again after the brakes are released.
Speed Limit Adjustment: The speed limit adjustment feature controls the top speed of the motor and is variable from 0-100% top speed. It uses a 10K ohm potentiometer mounted on the end of the two orange wires and is adjustable with a small flathead screwdriver.
