The Victron Energy Smart BatteryProtect 48V-100A protects 48V battery systems by disconnecting non-essential loads before excessive discharge and reconnecting them when voltage recovers. Rated for 100A continuous current and 250A peak, it uses spark-free MOSFET switching and can also serve as a remote system on/off switch.
Bluetooth and VictronConnect provide easy voltage-threshold programming and Instant Readout of warnings, alarms and errors. Li-ion mode supports external BMS control, while over-voltage protection disconnects loads above 64V. It installs close to the battery in a ventilated area; electronics are IP67 potted and connections are IP00.
