Description
xVictron VE.Bus BMS NG
The Victron VE.Bus BMS NG is a battery management system designed for use with Victron lithium battery systems connected via the VE.Bus interface. It provides cell protection, charge control and system coordination for lithium battery installations in off-grid, marine and mobile applications. This is a replacement and next-generation version of the original VE.Bus BMS, intended for professional installers working with Victron lithium battery banks.
Key Features
- Connects via VE.Bus to coordinate directly with compatible Victron inverters, inverter/chargers and chargers.
- Provides cell-level protection by signalling connected devices to stop charging or discharging when battery limits are reached.
- Next-generation design replacing the original VE.Bus BMS, with updated compatibility for current Victron lithium battery products.
- Lightweight at 0.217 kg, suitable for space-constrained installations in marine, vehicle and off-grid cabinet builds.
- Integrates with the wider Victron ecosystem including Venus OS devices for system monitoring and control.
- Supports pre-alarm outputs to allow controlled system shutdown before hard protection limits are triggered.
Product Overview
The VE.Bus BMS NG sits between the Victron lithium battery bank and the VE.Bus-connected inverter or inverter/charger. Its primary role is to protect the battery cells from conditions that would cause damage: overcharge, over-discharge and excessive temperature. When the BMS detects a cell approaching its limit, it sends a signal over VE.Bus to instruct the connected device to reduce or stop charging or discharging. This is a hardware-level protection mechanism, not purely software-based, which means it operates independently of any GX device or monitoring system.
The "NG" (Next Generation) designation indicates this unit supersedes the original VE.Bus BMS and is the current supported version for new installations. It is designed to work with Victron lithium batteries that use the VE.Bus BMS architecture. Installers upgrading existing systems or specifying new lithium installations should use this version rather than the legacy unit. Compatibility with specific battery models and firmware versions should be confirmed against Victron's current compatibility documentation before installation.
At 0.217 kg, the unit is compact and straightforward to mount within a battery enclosure or distribution board. It does not replace a full-featured BMS on batteries that have their own integrated management, but rather acts as the system-level coordinator between the battery and the inverter/charger on VE.Bus-based systems.

Installation Notes
The VE.Bus BMS NG must be installed by a qualified electrician or experienced Victron installer familiar with lithium battery systems and VE.Bus architecture. Lithium battery installations carry specific risks if protection systems are incorrectly wired or configured. Confirm battery and firmware compatibility before installation. This unit is not suitable for use with non-Victron batteries or batteries with their own integrated BMS that do not use the VE.Bus BMS communication protocol.
