The Victron Smart BatteryProtect 48V-100A safeguards your 48V battery bank from permanent damage by automatically disconnecting non-essential loads before the battery is drained flat. Built-in Bluetooth makes setup effortless right from your smartphone or tablet via the free VictronConnect app, letting you choose exact disconnect and reconnect voltages in seconds—or pick from nine pre-set levels using the physical setup pin.

Power flows in one direction from the IN terminal to the OUT terminal, so your battery connects to IN when controlling loads, or your charger connects to IN when controlling a charge source. Bluetooth can also be switched off whenever needed, delivering a simple, dependable battery protector for off-grid homes, cabins, and commercial backup systems.
