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 resumes running when the brake is released.
