Battery Management System VE.Bus BMS NG

The VE.Bus BMS NG is a comprehensive battery management system (BMS) for Victron Lithium NG batteries (not compatible with Lithium Battery Smart batteries), developed for systems with Victron inverters or inverters/chargers with VE.Bus communication. It monitors and protects the batteries against over- and undervoltage of each individual cell as well as against over- and undertemperature.

Thanks to integrated Bluetooth, the BMS enables centralised monitoring via VictronConnect. The BMS determines all important parameters such as voltage, current, state of charge and individual cell data directly from the battery, so no separate SmartShunt is required.

The lithium-NG batteries can be configured in series, parallel or a combination of both and support 12 V, 24 V and 48 V systems. A maximum of 50 batteries can be used in 12 V or 24 V banks and 25 batteries in 48 V banks, allowing storage of up to 192 kWh (12 V), 384 kWh (24 V) and 128 kWh (48 V). Multiple Lynx Smart BMS devices can be connected in parallel to expand capacity and provide 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 displays important data such as SoC, battery temperature, warnings and alarms directly in the device list without the need to connect.
• Load disconnect output: Controls the input for remotely switching on/off a BatteryProtect, inverter, DC-DC converter or other loads with remote switching function to prevent deep discharge.
• Charge disconnect output: Controls the connection for switching on/off chargers such as the Smart IP43 charger, a Cyrix-Li-Charge relay, a Cyrix-Li-ct battery coupler or a BatteryProtect to prevent overvoltage.
• Pre-alarm output: Provides early warning of low battery voltage before loads are switched off. Can control a relay, LED or audible alarm.
• Remote on/off control: Allows external control of load and charge disconnect outputs.
• LED indicators: Includes a blue LED for Bluetooth status and a red LED for warnings and faults.
