Victron VE.Bus BMS V2 for 12-48V Lithium Batteries - 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 VE.Bus BMS V2 is a sophisticated Battery Management System designed to provide comprehensive protection and monitoring for Victron Lithium Iron Phosphate (LiFePO4) batteries ranging from 12V to 48V. This system seamlessly integrates with Victron inverters and inverter/chargers that utilize VE.Bus communication, ensuring optimal battery performance and safety in various off-grid or backup power applications. The BMS continuously monitors individual cell voltages and temperatures, safeguarding against overvoltage, undervoltage, and temperature extremes to maximize battery lifespan and reliability.
Its advanced features include generating pre-alarm signals for imminent cell undervoltage conditions, enabling early intervention to prevent damage. In the event of critical conditions, the BMS can disable inverting functions and loads through the VE.Bus interface, and disconnect charging sources to protect the battery pack from overvoltage or thermal issues. The system's design allows for easy integration with Victron GX devices and supports remote control functionalities, including remote on/off switching and load/charge disconnection, enhancing system flexibility and management.
The next-generation VE.Bus BMS V2 expands on the original with added capabilities such as remote control terminals, the ability to disable solar chargers via VE.Direct and VE.Can connections, and auxiliary power inputs for maintaining GX device operation during system shutdowns. These enhancements facilitate more sophisticated energy management strategies and improve overall system robustness, making it suitable for complex, multi-device setups. The BMS is ideal for users seeking a reliable, feature-rich solution to protect their lithium battery investments and optimize system performance in various renewable energy applications.
