Victron Battery Management System 12.8V/25.6V Lithium Battery Protection, BMS, Over- and Undervoltage Protection

The VE.Bus BMS and VE.Bus BMS V2 are battery management systems (BMS) designed for connecting and protecting one or more 12.8 V and 25.6 V Lithium Battery Smart batteries (LiFePO4 or LFP) in systems with Victron inverters or inverter/chargers with VE.Bus communication. It monitors and protects the batteries against over- and undervoltage of each individual cell, as well as against over- and undertemperatures.

Depending on the status of the battery(ies), the BMS will:

• Generate a pre-alarm signal to warn of an impending cell undervoltage.
• Disable inversion in VE.Bus inverters or inverter/chargers via VE.Bus and disconnect other loads via the "Load Disconnect" terminal in case of cell undervoltage.
• Disable charging in VE.Bus inverters or inverter/chargers via VE.Bus and disable other chargers via the Disconnect Charging terminal in case of cell overvoltage, undertemperature or overtemperature.
• Terminals for remote switching on and off.
• Ability to disable VE.Direct and VE.Can solar chargers via a GX device.
• Ability to control the VE.Bus inverter/charger from multiple devices, such as the Digital Multi Control, the VE.Bus Smart Dongle and/or a GX device.
• Auxiliary input and output terminals that allow a GX device to remain powered in the event of a system shutdown.
