VE.Bus BMS NG - For Victron Lithium NG Batteries

The VE.Bus BMS NG serves as a comprehensive Battery Management System (BMS) specifically designed for Victron Lithium NG batteries (it is not compatible with Lithium Battery Smart batteries). This system is intended for use with Victron inverters or inverter/chargers that utilize VE.Bus communication. It effectively monitors and safeguards the batteries against overvoltage and undervoltage conditions of any individual cell, as well as overtemperature and undertemperature scenarios.

Equipped with integrated Bluetooth, it establishes a direct connection to all lithium NG batteries within the system, allowing for centralized monitoring through VictronConnect. Additionally, it obtains current and state of charge information directly from the batteries, eliminating the necessity 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.

• 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.
