LBD14 - Protection Circuits

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 20.5 volts, but varies from controller to controller.)
Power Cut Off During Braking
When underway the brake switch signals the
controller to cut the battery output.
