CT-660B9 - Protection Circuits

Current Limiting
This prevents the motor current from exceeding the specified value avoiding damage to the motor and the controller due to over current conditions.
Under Voltage Protection
When battery voltage falls to a specified value, the controller cuts off battery output preventing over discharge and extending battery life.
(The cutoff value is approximately 30.5± 0.5 volts, but varies drastically from controller to controller.)
Power Cut Off During Braking
When underway the brake switch signals the controller to cut the battery output.
