Description

Overview

The Victron VE.Bus BMS NG is a complete Battery Management System designed exclusively for Victron Lithium NG batteries. It is intended for use in systems with Victron inverters or inverter/chargers that communicate via VE.Bus, providing centralised monitoring, protection and system control.

The VE.Bus BMS NG continuously monitors individual cell voltage and battery temperature, protecting the system from overvoltage, undervoltage, and over-temperature or under-temperature conditions. With built-in Bluetooth and direct battery communication, it simplifies system design while delivering advanced protection and scalability for residential, commercial and off-grid energy storage systems.
