Battery protection

The battery protector disconnects the battery from non-essential loads before it is fully discharged (which would damage the battery) or before it has insufficient capacity to start the engine.

Victron Energy BatteryProtect is a one-way device. It can only handle current in one direction so it's either current to a load or current from a charger, but not both currents at the same time. Also, current can only flow from the battery terminal to the load terminal. If used with a load, the battery is connected to the battery terminal and if used with a charger, the charger is connected to the battery terminal.
