Victron Energy Smart Battery Protect

The Smart BatteryProtect disconnects the battery from the less important loads before it is completely discharged (which would damage it) or before it has run out of power to start the engine.

By using Bluetooth to program the Smart BatteryProtect, you can set all required on / off thresholds. Alternatively, one of nine pre-set on / off thresholds can be set using the programming pin (see manual).
