Victron Energy VE.Bus BMS NG Battery Management System for Lithium NG Batteries

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 theres 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.

The Victron Energy VE.Bus BMS NG is an advanced all-in-one battery management system designed specifically for Victron Lithium NG batteries. It effectively monitors and protects your battery bank against overvoltage, undervoltage, and temperature extremes, ensuring optimal performance and safety. Compatible with system voltages of 12V, 24V, and 48V, it supports configurations of series and parallel batteries, allowing you to tailor your energy storage to your needs. With the capability to handle up to 50 batteries in 12V or 24V systems and 25 in 48V systems, it offers a maximum storage capacity of 192 kWh for 12V, 384 kWh for 24V, and 128 kWh for 48V setups, making it suitable for a wide range of applications including off-grid power, RVs, and renewable energy systems. Built-in Bluetooth enables seamless wireless connection via the VictronConnect app for real-time monitoring, configuration, and firmware updates, eliminating the need for additional hardware like SmartShunt. It receives current and state of charge data directly from the batteries, providing accurate system insights at a glance. The system supports flexible battery arrangements—series, parallel, or a combination—allowing for versatile system design. Multiple BMS units can be paralleled to expand capacity or add redundancy, ensuring system reliability. Features include load and charge disconnect outputs for remote control of connected devices such as BatteryProtects or chargers, pre-alarm functions for early low-voltage warnings, and remote on/off control for integrated system management. LED indicators provide visual status updates, with a blue LED indicating Bluetooth connectivity and a red LED signaling warnings or errors. This comprehensive BMS offers a reliable, scalable solution for managing high-capacity lithium battery systems with ease and confidence, backed by detailed user documentation available online.
