Victron Battery Protect BP220 (220 Amp / M8 Stud)

The Victron BatteryProtect BP220 is a heavy-duty battery protection device designed to prevent excessive battery discharge by automatically disconnecting non-essential loads before battery voltage reaches damaging levels. Suitable for motorhomes, campervans, caravans, boats, off-grid solar systems, commercial vehicles, and backup power installations, the BP220 helps maximise battery life while protecting connected equipment from low-voltage conditions.

Designed for both 12V and 24V battery systems, the BatteryProtect automatically detects system voltage and can be programmed with multiple disconnect and reconnect voltage thresholds. A built-in seven-segment display simplifies setup, while integrated alarm outputs provide advance warning before load disconnection occurs. The unit uses solid-state MOSFET switching technology rather than mechanical relays, ensuring silent, spark-free operation and high reliability.

The BP220 is compatible with AGM, Gel, Flooded Lead-Acid, and Lithium battery systems, including integration with Victron VE.Bus BMS systems for lithium battery protection.

Technical Specifications

Advanced Protection Features

Deep Discharge Protection

The BP220 automatically disconnects loads before the battery becomes excessively discharged, preventing permanent battery damage and helping preserve available capacity.

Programmable Voltage Thresholds

Users can select multiple predefined voltage settings for disconnect and reconnect operation. The integrated display clearly shows the selected configuration.

Delayed Alarm & Disconnect

• Alarm activates after low voltage persists for 12 seconds.
• Load disconnect occurs 90 seconds later.
• Loads automatically reconnect 30 seconds after battery voltage recovers above the reconnect threshold.

Over-Voltage Protection

Connected loads are automatically disconnected if system voltage exceeds safe limits (approximately 16V on 12V systems or 32V on 24V systems), helping protect sensitive electronics.

Lithium Battery Compatibility

The BP220 includes a dedicated lithium mode and can work directly with:

• Victron VE.Bus BMS
• Victron VE.Bus BMS V2
• Victron Lithium Battery Smart systems

It can also be used as a charge interrupter between a charger and lithium battery bank when required.

Ideal Applications

• Large campervan electrical systems
• Motorhomes
• Caravans
• Marine and yacht installations
• Off-grid solar systems
• Lithium battery systems
• Backup power systems
• Commercial vehicles
• Telecommunications equipment
• High-power inverter installations up to 220A load current
