Victron BatteryProtect 220A
12V/24V Automatic Over-Discharge & Over-Voltage Protector | Model: BP-220 (VE-BPR220)
The Victron BatteryProtect 220A (model BP-220, SKU: VE-BPR220) is an essential device designed to safeguard your 12V or 24V battery systems from damaging over-discharge and over-voltage conditions. This intelligent protector automatically disconnects non-essential loads when battery voltage drops too low, preserving battery health and extending its lifespan.
With its robust 220A continuous current rating and automatic system voltage recognition, the BP-220 is suitable for a wide range of applications, from off-grid solar setups and marine systems to RVs and backup power solutions. It also features over-voltage protection to shield sensitive appliances from high voltage spikes.
IMPORTANT NOTE: This BatteryProtect unit is designed for one-directional current flow. Ensure correct installation on the positive battery cable, close to the battery.

Common Questions
What does a BatteryProtect do?
A BatteryProtect prevents damage to your battery by disconnecting non-essential loads when the battery voltage drops below a safe level (low voltage disconnect) or rises too high (over-voltage disconnect). This protects both the battery and connected appliances.
Is the Victron BatteryProtect compatible with Lithium batteries?
Yes, the Victron BatteryProtect 220A is compatible with Lithium batteries. It features specialised modes that allow it to function as a charge interrupter when used with a Victron Ve.Bus Lithium Battery Management System (BMS).
Can I use the BatteryProtect between a battery and a charger?
Generally, the BatteryProtect should not be installed between a battery and a battery charger, as it is designed for one-directional current flow (from battery to load). However, it can be used in specialised systems, such as a charge interrupter for Lithium batteries when controlled by a BMS. Always refer to the detailed user manual for specific wiring diagrams and recommendations.
How do I program the low-voltage disconnect settings?
The Victron BatteryProtect 220A features programmable low-voltage thresholds. Programming is typically done via a simple setup procedure using a dedicated pin or button sequence, as detailed in the comprehensive user manual supplied with the unit.
