The Victron Smart BatteryProtect guards your battery against excessive discharge while acting as a reliable system on/off switch for essential loads. Designed for boats, RVs, caravans, and automotive setups, it keeps crucial power available when you need it most.
-
Current rating: 220 A maximum switching capacity for auxiliary loads
-
Voltage range: 6–35 VDC operating range with 12/24V auto-ranging and a one-time voltage detection to simplify installation
-
Bluetooth programming: Bluetooth-based engage/disengage level adjustment directly from your device; nine predefined levels; programming pin for exact control; Bluetooth can be disabled if needed
-
Li-ion optimized mode: Li-ion optimized mode supports VE.Bus BMS control and can function as a charge interrupter between a charger and a Li-ion battery
-
Low idle current: Ultra-low current consumption minimizes parasitic drain, especially important for Li-ion systems after low-voltage shutdown
-
Over-voltage protection: Disconnects the load if voltage rises above 16.3V (32.6V in higher configurations)
-
Ignition-proof switches: Ignition-proof MOSFET switches provide safe, spark-free operation in automotive environments
-
Alarm and load delays: Delayed alarm output activates only after voltage stays below the preset level for more than 12 seconds; Delayed load disconnect/reconnect disconnects the load for 90 seconds after low voltage, and automatically reconnects 30 seconds after voltage rises above the threshold
-
Versatile applications: Ideal for boats, RVs, caravans, and automotive setups seeking battery protection, extended life, and essential power with Bluetooth programming or VE.Bus BMS integration
The Smart BatteryProtect helps prevent battery damage by automatically disconnecting non-essential loads before deep discharge occurs, preserving power for critical functions like engine starting. Its 12/24V auto-ranging with a one-time voltage detection simplifies setup, while Bluetooth programming offers convenient on-device threshold adjustments and the option to disable Bluetooth if a fixed setup is preferred. Li-ion optimized mode enhances compatibility with VE.Bus BMS and can act as a charger interlock, protecting modern battery chemistries. Ultra-low parasitic drain extends battery life between uses, and over-voltage protection shields sensitive loads from voltage spikes. Ignition-proof MOSFETs ensure spark-free operation in automotive environments. Delayed alarm and load-delays reduce nuisance alerts during startup and provide stable power management. Suitable for marine, recreation, and automotive installations, it delivers flexible control, safer power, and longer battery life.
