Victron BatteryProtect 12/24V - 100A

The 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. It also provides an alternative to disable chargers without a remote on/off port to protect from over-voltage. Compared to the Smart BatteryProtect, the BatteryProtect must be programmed via the PROG pin to GND pin method. The BatteryProtect is a uni-directional device. It can only deal with current in one direction, so either current to a load, or current from a charger, but not both currents at the same time. In addition to this, current can only flow from the IN terminal to the OUT terminal.
