Victron BatteryProtect 48V 100A Disconnect

The Victron BatteryProtect (48V, 100A) disconnects the battery from nonessential loads before it's completely discharged or before it has insufficient power left to crank the engine. It is designed for boaters who want straightforward battery protection without Bluetooth complexity.

This is a unidirectional device, handling current in only one direction, either to a load or from a charger, but not both simultaneously. Current can only flow from the Battery terminal to the Load terminal: when used with a load, the battery connects to the Battery terminal, and when used with a charger, the charger connects to the Battery terminal.
