Victron VE Bus BMS NG Battery Management for Lithium NG

Introducing the VE.Bus BMS NG, an all-in-one Battery Management System designed for Victron Lithium NG batteries. Not compatible with Lithium Battery Smart batteries, this BMS is built for systems with Victron inverters or inverter/chargers using VE.Bus communication, delivering comprehensive monitoring and protection for your battery bank.

Key Features

• All-in-one BMS for safe, reliable lithium battery management
• VE.Bus communication compatibility with Victron inverters and inverter/chargers
• Monitoring and protection for voltage, current, temperature, and battery health
• Optimized for Lithium NG chemistry for best performance
• Seamless integration with existing Victron systems for user-friendly operation
• Excludes compatibility with Lithium Battery Smart batteries

Benefits

The VE.Bus BMS NG helps maximize battery lifespan and protect against overvoltage, undervoltage, overcurrent, and temperature extremes. By sharing real-time data via VE.Bus, it enables precise energy flow control between your inverter/charger, battery bank, and other Victron components.

Why It Matters

Choose the VE.Bus BMS NG for a compact, reliable solution that simplifies setup and ensures safe, efficient operation of your Lithium NG battery system. Ideal for off-grid or mobile installations where Victron hardware is already in use.

VE.Bus BMS NG

The VE.Bus BMS NG is an all-in-one Battery Management System (BMS) for Victron Lithium NG batteries (not compatible with Lithium Battery Smart batteries), designed for systems with Victron inverters or inverter/chargers using VE.Bus communication. It monitors and protects the batteries against overvoltage and under-voltage of any individual cell, and also against over-temperature or under-temperature conditions.

With built-in Bluetooth, it connects directly to all lithium NG batteries in the system for central monitoring via VictronConnect. It also receives current and state of charge data directly from the batteries, so there’s no need for a separate SmartShunt.

The lithium NG batteries can be configured in series, parallel, or a combination of both, supporting 12V, 24V, and 48V systems. A maximum of 50 batteries can be used in 12V or 24V banks, and 25 batteries in 48V banks, enabling up to 192 kWh (12V), 384 kWh (24V), and 128 kWh (48V) of storage. Multiple Lynx Smart BMS units can be paralleled to expand capacity and ensure redundancy.

Features:

• Bluetooth Smart: The VE.Bus BMS NG includes Bluetooth Smart for wireless configuration, monitoring, and firmware updates via the VictronConnect App. Instant Readout shows key data such as SoC, battery temperature, warnings, and alarms directly in the device list, without needing to connect.
• Load disconnect output: Controls the remote on/off input of a BatteryProtect, inverter, DC-DC converter, or other loads with remote on/off functionality to prevent deep discharge.
• Charge disconnect output: Controls the remote on/off port of chargers such as the Smart IP43 Charger, a Cyrix-Li-Charge relay, a Cyrix-Li-ct Battery Combiner, or a BatteryProtect, to prevent overvoltage.
• Pre-alarm output: Provides early warning for low battery voltage before disconnecting loads. Can drive a relay, LED, or buzzer.
• Remote on/off control: Allows external control of both load and charge disconnect outputs.
• LED indicators: Includes a blue LED for Bluetooth status and a red LED for warnings and errors.
