| 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
20 Volts ± 0.5 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. |
