Description
The Victron BatteryProtect BP-100 is a robust 100A protection device for 6–35 VDC systems. It prioritizes essential loads to prevent deep discharge and insufficient cranking power, helping you stay powered and protect battery health across automotive, marine, and solar setups. 
- Current rating: 100A continuous current handling for 6–35 VDC systems.
- Auto-ranging 12/24V: Automatically detects system voltage, simplifying setup across common vehicle and marine power configurations.
- Voltage-based control: Engage/disengage at multiple preset voltages with a seven-segment display indicating the active setting.
- Li-ion compatibility: Dedicated Li-ion mode and controllable via VE.Bus BMS; can act as a charge interrupter between charger and Li-ion battery.
- Ultra-low current consumption: Minimizes parasitic drain, especially important after a low-voltage shutdown with Li-ion chemistries.
- Overvoltage protection: Automatically disconnects the load if voltage exceeds 16V (or 32V in high-range) to protect sensitive equipment.
- Ignition-safe operation: MOSFET-based switching eliminates sparks and is suitable for ignition-protected environments.
- Alarm and delay features: Delayed alarm output (open-collector up to 50 mA) triggers if voltage stays below disconnect threshold for more than 12 seconds; the load disconnects after 90 seconds and reconnects 30 seconds after voltage returns above the threshold.
- VE.Bus BMS coordination: In Li-ion configurations, coordinates with Victron VE.Bus BMS for seamless battery management.
- Safety and compliance: Warning: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.
BP-100 helps you manage power proactively by prioritizing essential loads, protecting battery health, and preventing unexpected outages. With auto-ranging 12/24V, it fits a wide range of vehicles, boats, and off-grid systems. The Li-ion mode and VE.Bus BMS compatibility support modern battery chemistries, while the ignition-safe MOSFET switching reduces spark risk in engine compartments. The built-in alarm and delayed disconnect/reconnect logic provide warnings and safe power transitions, giving you time to react without sacrificing critical systems.
