Meet the Victron BatteryProtect BP-220 — a high-current, auto-ranging protection device designed for 6-35 VDC systems. With a 220A rating, it automatically disconnects non-essential loads before deep discharge or before you lose crank power, safeguarding your battery bank and essential electronics.
Key perks you’ll love include:
-
12/24V auto-ranging for seamless integration in mixed power systems
-
Programmable voltage thresholds with a seven-segment display that clearly shows the selected setting
-
Li-ion compatibility with a special setting that can be controlled by the VE.Bus BMS
- Can function as a charge interrupter between a charger and a Li-ion battery
-
Ultra-low current consumption— crucial for Li-ion setups after low-voltage shutdown
-
Over-voltage protection disconnects the load if voltage rises above 16V (or 32V in applicable configurations)
-
Ignition-proof MOSFET switches— no relays and no sparks
-
Delayed alarm output with open-collector, negative-rail connection (up to 50 mA) to drive buzzers, LEDs or relays
-
Delayed load disconnect/reconnect disconnects 90 seconds after alarm activation; reconnects 30 seconds after voltage recovers above the reconnect threshold
Designed for marine, automotive, RV and off-grid applications, the BP-220 protects your battery investment while ensuring vital systems stay powered when you need them most.
