Never worry about your boat's battery again. Battery Brain Marine Type III attaches directly to your battery's positive terminal, constantly monitoring power. It automatically disconnects the battery from the electrical system when the charge drops near the minimum level required to start the motor. The battery can't drain any further, and you'll have adequate power to start the motor.

If you're worried about theft, use the remote control to disconnect the battery and prevent someone from starting or hot-wiring your boat. You can use the included remote control to turn on the unit or to reconnect the circuit. Warranty: 2 years.
