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.
Note About Connectors: The Charger Port and Brake Light connectors with black and red wires have printed labels on them that say what their functions are. These labels are facing down and not visible in the photograph of the controller shown above. The Power Light connector with black and red wires does not have a printed label on it.
