Victron Energy VE.Bus BMS V2 for Lithium Batteries 12-48VDC – Compatible with All VE.Bus and GX Devices

VE.Bus BMS V2 for Victron LiFePO4 Batteries 12-48VDC - Work with All VE.Bus GX Devices

The VE.Bus BMS and VE.Bus BMS V2 is Battery Management System (BMS) designed to interface with and protect a single or multiple Victron Lithium Battery 12,8V 25,6V Smart (LiFePO4 or LFP) in systems that have Victron inverters or inverter/chargers with VE.Bus communication. It monitors and protects the batteries against the over voltage and under voltage of any individual cell, and also over temperature or under temperature conditions.

Based on the status of the battery or batteries, the BMS will:

• Generate a pre-alarm signal to alert of an imminent cell under voltage conditions.


• Disable inverting in VE.Bus inverters or inverters/chargers via VE.Bus, and disable other loads via the 'Load Disconnect' terminal in the event of a cell under voltage conditions.


• Disable charging in VE.Bus inverters or inverters/chargers via VE.Bus and disable other chargers via the 'Charge Disconnect' terminal in the event of a cell overvoltage, under-temperature, or over-temperature conditions.


• The "original" VE.Bus BMS is best used in systems without a GX device

The "next generation" VE.Bus BMS V2 has additional features such as:

• Remote on/off terminals.


• Ability to disable VE.Direct and VE.Can solar chargers via a GX device.


• Allowing control of the VE.Bus inverter/charger from multiple devices, like the Digital Multi Control, the VE.Bus Smart dongle and/or a GX device.


• Auxiliary power input and output terminals that allow a GX device to remain powered in the event of a system shutdown.

The Victron Energy VE.Bus BMS V2 is a sophisticated battery management system designed specifically for Victron Lithium Iron Phosphate (LiFePO4) batteries operating between 12 and 48 volts DC. This BMS seamlessly integrates with Victron inverters, inverter/chargers, and GX devices to provide comprehensive battery protection and monitoring. It safeguards against overvoltage, undervoltage, and temperature extremes on individual cells, ensuring optimal battery health and longevity. The system actively monitors battery status, issuing pre-alarm signals for imminent under-voltage conditions and automatically disabling inverting and charging functions when critical thresholds are exceeded. This proactive approach prevents damage due to electrical or thermal stress, maintaining system reliability and safety. The BMS’s compatibility with a wide range of Victron products makes it suitable for various off-grid, marine, or mobile power applications, offering users flexible installation options. The original version of the VE.Bus BMS is tailored for systems without GX devices, while the V2 model introduces advanced features such as remote on/off control, the ability to disable solar chargers via GX, and auxiliary power terminals. These enhancements facilitate more integrated system management, allowing control from multiple devices like the Digital Multi Control, VE.Bus Smart dongle, or GX unit. Additionally, the auxiliary power input and output terminals ensure that a connected GX device remains operational even during system shutdowns, providing continuous monitoring and control. The BMS is compact and lightweight, making installation straightforward, and comes with detailed documentation available online for setup and troubleshooting. Whether used in a standalone battery system or integrated into a larger renewable energy setup, the Victron VE.Bus BMS V2 offers robust protection, remote control capabilities, and seamless integration with Victron’s ecosystem to optimize battery performance and lifespan.
