Victron Smart BatteriesProtect 12/24V-65A

Smart BatteryProtect disconnects the battery from non-essential loads before it is fully discharged (which would damage the battery) or before it is insufficient to start the engine. When using Bluetooth to program Smart BatteryProtect, any level of switching on and off can be set. Alternatively, one of the nine predefined switch-on and switch-off levels can be set with the programming pin. Bluetooth can be deactivated if necessary. The Smart BatteryProtect is a one-way device. It can only handle power in one direction so it is either power to a load or power from a charger, but not both streams at the same time. Also, the current can only flow from the IN terminal to the OUT terminal. If used with a load, the battery is connected to the IN terminal and if used with a charger, the charger is connected to the IN terminal.
