VE.Bus BMS NG

The VE.Bus BMS NG is an all-in-one Battery Management System (BMS) for Victron Lithium NG batteries, designed for systems with Victron inverters or inverter/chargers using VE.Bus communication (MultiPlus, Quattro). It monitors and protects the batteries against over voltage and under voltage of any individual cell, and also over temperature or under temperature conditions.

With built-in Bluetooth, the BMS provides central monitoring via VictronConnect. It derives all key parameters, including voltage, current, state of charge and individual cell data, directly from the battery, removing the 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.

Compatibility: Victron Lithium NG batteries only. Not compatible with the Lithium Battery Smart range.

Key features:

• Bluetooth Smart: wireless configuration, monitoring and firmware updates via the VictronConnect app. Instant Readout shows SoC, battery temperature, warnings and alarms directly in the device list.
• Load disconnect output: controls the remote on/off input of a BatteryProtect, inverter, DC-DC converter or other loads with remote on/off, 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: early warning for low battery voltage before loads are disconnected. Can drive a relay, LED or buzzer.
• Remote on/off control: external control of both the load and charge disconnect outputs.
• LED indicators: blue LED for Bluetooth status and red LED for warnings and errors.
