The Victron BatteryProtect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The BatteryProtect is not designed for reverse currents from charging sources. The BP is designed to allow current to flow from IN (battery) to OUT (load) terminals only. Reverse currents from OUT to IN terminals are strictly forbidden, and will damage the device. If you wish to use the BP as a disconnection for a charge source, you must orient the unit in the system so that the current is flowing in the intended direction, IN to OUT. Features Ignition proof 12/24 Volt auto-ranging Ultra-low current consumption Easy to set up different engage/disengage Voltages via 7-segment LED display
