Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth Capable
Features:
- Protects the battery against excessive discharge and can be used as a system on/off switch The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The on/off input can be used as a system on/off switch.
- 12/24V auto ranging The Smart BatteryProtect automatically detects system voltage one time only.
- Bluetooth: programming made easy When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set. Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin (see manual). If required, Bluetooth can be disabled.
- A special setting for Li-ion batteries In this mode the BatteryProtect can be controlled by the VE.Bus BMS. Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual.
- Ultra-low current consumption This is important in case of Li-ion batteries, especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.
- Over voltage protection To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V.
- Ignition proof No relays but MOSFET switches, and therefore no sparks.
- Delayed alarm output The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.
- Delayed load disconnect and delayed reconnect The load will be disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.

The Victron Energy Smart BatteryProtect model BPR122022000 is a high-performance device designed to safeguard your battery system from over-discharge and over-voltage conditions, ensuring longevity and reliable operation. With a current handling capacity of up to 220 amps, it is suitable for a wide range of automotive, marine, and renewable energy applications. The device automatically detects system voltage, supporting both 12V and 24V configurations, and features Bluetooth connectivity for simple, intuitive programming from your smartphone or tablet. This allows you to easily adjust engage and disengage voltage levels or choose from nine predefined settings, providing flexibility for different battery types and system requirements.
The Smart BatteryProtect includes a special mode for lithium-ion (Li-ion) batteries, which can be managed via the VE.Bus BMS. It functions effectively as both a protective disconnect and a charge interrupter between the charger and Li-ion batteries, preventing damage caused by overcharging or deep discharge. The device's ultra-low current consumption is particularly beneficial for Li-ion systems, especially after low voltage shutdown, helping to preserve battery life. It also features over-voltage protection, disconnecting the load if voltage exceeds 16.3V or 32.6V, thereby protecting sensitive electronics from voltage spikes.
Built with safety and durability in mind, the Victron Smart BatteryProtect is ignition proof, using MOSFET switches instead of relays, eliminating sparks and increasing reliability. Its delayed alarm output can activate a buzzer, LED, or relay if the battery voltage remains below the set threshold for more than 12 seconds, providing early warning of potential issues. Additionally, the device offers delayed load disconnection and reconnection—disabling the load 90 seconds after low voltage detection and reconnecting 30 seconds after voltage recovery—helping to prevent sudden power disruptions during engine start or similar events. This robust protection makes the Victron Energy Smart BatteryProtect an essential component for maintaining battery health and system safety.
