Description
xSmart BatteryProtect 12/24V-220A — BPR122022000
The Victron Smart BatteryProtect 12/24V-220A is a programmable battery protection device designed to disconnect non-essential DC loads before a battery reaches a damaging depth of discharge. It is suited to off-grid, marine, vehicle and backup power installations where over-discharge protection is critical to battery longevity.
Key Features
- Rated at 220A continuous DC load current on 12V or 24V systems, with no voltage conversion losses.
- Bluetooth connectivity via the VictronConnect app allows wireless configuration, threshold adjustment and real-time monitoring from a smartphone or tablet.
- Programmable disconnect and reconnect voltage thresholds to suit different battery chemistries including lead-acid and lithium.
- Remote on/off input accepts a signal from a battery management system (BMS) or other control device, enabling integration into more complex systems.
- Extremely low self-consumption, minimising parasitic drain on the battery when the load is disconnected.
- Alarm output provides a pre-disconnect warning signal, allowing connected equipment to shut down gracefully before power is cut.
- Compatible with 12V and 24V battery banks, making it suitable for a wide range of DC system voltages without requiring separate models.
Product Overview
The Smart BatteryProtect monitors battery voltage continuously and disconnects the load circuit when voltage drops to a user-defined threshold. This prevents deep discharge events that permanently reduce battery capacity, particularly in lead-acid chemistries. Once the battery recovers to the reconnect voltage (also user-defined), the load is automatically restored. The delay between reconnect voltage being reached and load restoration is configurable, which helps avoid rapid cycling in partially discharged conditions.
The Bluetooth integration sets this unit apart from basic battery protects. Using VictronConnect, an installer can configure all thresholds wirelessly without needing to access the unit physically after installation. This is particularly useful in confined or hard-to-reach installations such as under-floor battery compartments, engine bays or enclosed cabinetry. The same app provides live voltage readings and historical data, which aids fault-finding and commissioning.
The remote on/off input is an important feature for lithium battery systems. A lithium BMS can use this input to force a disconnect independently of voltage thresholds, providing an additional layer of protection. The alarm output can be wired to a warning indicator or to the remote shutdown input of an inverter or charger, giving the system time to respond before the load is cut.

Applications
- Off-grid solar systems where battery over-discharge protection is required for DC loads.
- Marine and narrowboat installations protecting 12V or 24V house battery banks from excessive discharge.
- Motorhome and campervan leisure battery systems with high-current DC appliances.
- Vehicle auxiliary power systems where a secondary battery bank supplies accessories independently of the starter battery.
- Backup power systems requiring automatic load shedding when battery voltage falls below a safe threshold.
- Lithium battery installations where BMS remote control of load disconnection is required.
What Is Included
- 1x Victron Smart BatteryProtect 12/24V-220A (BPR122022000)
Installation Notes
The Smart BatteryProtect must be installed in the load circuit only, between the battery and the DC loads. It is not designed to be placed in a charge circuit and must not be used to disconnect a charger from the battery. For lithium battery systems, connection of the BMS remote signal to the on/off input is strongly recommended. Installation should be carried out by a qualified electrician or experienced DC systems installer. Ensure appropriate fusing is in place on the battery side of the unit in accordance with wiring regulations.
