Product Details

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 over voltage and under voltage of any individual cell, and also 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.

Key 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.
Product Specifications

System Compatibility & Sizing

  • Battery Compatibility: Victron Lithium NG batteries (12.8 V, 25.6 V, 51.2 V).
  • System Voltages: 12 V, 24 V, or 48 V systems.
  • Battery Bank Sizing (12V & 24V): Supports up to 50 batteries (Max 192 kWh for 12V; 384 kWh for 24V).
  • Battery Bank Sizing (48V): Supports up to 25 batteries (Max 128 kWh).
  • Inverter Integration: Directly controls VE.Bus inverters or inverter/chargers in the event of cell alarms.

Protection & Control

  • Cell Protection: Monitors individual cells via M8 circular connector cables and signals disconnects for safety.
  • Load Disconnect Terminal: High/free floating, 1 A. Triggers in case of cell undervoltage.
  • Charge Disconnect Terminal: High/free floating, 10 mA. Triggers in case of cell overvoltage or temperature alarms.
  • Pre-alarm Terminal: Free floating/high. Provides an early warning before a load disconnect occurs.
  • Auxiliary Output: 1 A.
  • Auxiliary Input: 1 A.
  • Remote On/Off Terminal: Yes; supports manual or system-driven toggling via physical terminal or the VictronConnect app.

Connectivity & Monitoring

  • Bluetooth Smart: Built-in for monitoring, operation, and configuration via the VictronConnect app.
  • Instant Readout: Essential battery data is displayed via Bluetooth without the need for pairing.
  • Data Communication: Features VE.Bus communication for direct connection with inverter/chargers and GX devices (e.g., Cerbo GX).
  • DVCC Control: Fully supports Distributed Voltage and Current Control (DVCC). It can control compatible inverter/chargers and solar chargers via a GX device without needing the physical disconnect terminals.
  • Battery Monitoring: Integrated through the Lithium NG batteries, which feature internal shunts to send SoC, voltage, cell voltage, temperature, and balancer status to the BMS.

Physical Specifications

  • Dimensions (h x w x d): 24 x 95 x 106 mm
  • Unit Weight: 0.12 kg
  • Protection Category: IP20
  • Mounting: Compact form factor designed for easy integration into electrical cabinets.

System Design Recommendations: The VE.Bus BMS NG is specifically recommended for 12 V, 24 V, or 48 V systems that include Victron VE.Bus inverter/chargers and a GX device. It is the ideal choice for systems requiring advanced digital integration, DVCC capabilities, and centralized control of both AC and DC charging sources.
