Victron BatteryProtect 48V-100A

Protect your power system with smart precision.
The Victron Smart BatteryProtect 48V-100A automatically disconnects your battery from non-essential loads before it becomes overly discharged—or when there's not enough power left to start your engine. Designed for 48V systems and packed with Bluetooth connectivity, this unit is ideal for off-grid solar, marine, telecom, and industrial energy systems.

Easily configure trip thresholds and reconnect points using the VictronConnect App, or use manual programming via the built-in display. With a peak current rating of 250A and IP67-rated electronics, this rugged, reliable device ensures your battery is never pushed past its limits.
