Victron VE.Bus BMS NG: Precision Battery Management for Lithium NG Systems

Engineered for Victron Lithium NG Batteries

The Victron VE.Bus BMS NG is a dedicated Battery Management System designed exclusively for Victron Lithium NG batteries. It communicates directly with Victron inverters and inverter/chargers via the VE.Bus protocol, ensuring coordinated protection and optimal performance. This unit is not compatible with Victron Lithium Battery Smart batteries.

Intelligent Monitoring and Control

This advanced BMS continuously monitors individual cell voltages and temperatures, safeguarding against over-voltage, under-voltage, and thermal extremes. Integrated Bluetooth Smart connectivity provides direct access to all Lithium NG batteries, enabling real-time monitoring of State of Charge (SoC) and current via the VictronConnect app. This eliminates the need for additional components like a SmartShunt, simplifying installation and reducing system complexity.

Scalable Architecture for Demanding Applications

The VE.Bus BMS NG supports large-scale energy storage configurations, making it suitable for a wide range of installations:

• Up to 50 batteries in 12V or 24V banks (maximum 192 kWh and 384 kWh respectively)
• Up to 25 batteries in 48V banks (maximum 128 kWh)

This scalability is ideal for caravan, RV, marine, off-grid, industrial, and tiny home energy systems. For even larger setups, multiple Lynx Smart BMS units can be paralleled for increased capacity and redundancy.

Comprehensive Protection Outputs

The BMS features multiple control outputs to manage system safety:

• Load Disconnect Output: Prevents deep discharge by controlling inverters, BatteryProtect units, and other loads.
• Charge Disconnect Output: Stops charging equipment to avoid over-voltage conditions.
• Pre-Alarm Output: Provides early warning of low voltage before load disconnection occurs.
• Remote On/Off: Allows external switching of both load and charge disconnects for flexible system control.
• LED Indicators: Display Bluetooth status and system warnings at a glance.

Built for Reliability in Harsh Environments

Housed in a compact, matte black ABS enclosure (23.2 mm x 95.0 mm x 105.8 mm), the VE.Bus BMS NG is rated IP20 and operates reliably in temperatures from -20°C to +50°C. Its low power consumption—just 10 mA during regular operation—minimises energy drain on the battery bank. The dual RJ45 VE.Bus ports enable seamless integration with Victron MultiPlus and Quattro inverter/chargers, while the 6-way terminal block simplifies wiring for battery, GX-power, and alarm outputs.

Streamlined Installation and Firmware Updates

With plug-and-play configuration and firmware update capability via the VictronConnect app, the VE.Bus BMS NG reduces setup time and ensures your system stays current with the latest features. Its direct battery communication eliminates the need for additional shunts or sensors, lowering overall system cost and complexity.
