The Victron VE.Bus BMS V2 for Victron LiFePO4 Batteries 12-48VDC is a next‑generation Battery Management System designed to interface with and protect one or multiple Victron LiFePO4 (LiFePO4/LFP) Smart batteries in systems that use VE.Bus inverters or inverter/chargers with VE.Bus communication. It continuously monitors cell voltages and temperatures to safeguard your pack and keep performance at its best.
Key capabilities
-
Full cell monitoring detects over voltage, under voltage, and temperature extremes to protect each cell in the pack.
-
Pre‑alarm signaling provides an early warning of imminent under-voltage conditions, allowing proactive action.
-
Load and inverter control automatically disables inverters/loads via VE.Bus when a cell under‑voltage is detected.
-
Charge protection automatically disables charging via VE.Bus and other chargers via the Charge Disconnect terminal in the event of over-voltage or extreme temperatures.
-
Remote on/off terminals advanced control for convenient system management.
-
GX integration can disable VE.Direct and VE.Can solar chargers through a GX device, and keep the GX powered during system shutdown via auxiliary power terminals.
-
Multi‑device control supports operation from multiple devices, including the Digital Multi Control, VE.Bus Smart dongle, and GX devices.
-
Auxiliary power for GX ensures the GX device remains powered even when the main system is shut down.
The original VE.Bus BMS is best used in systems without a GX device. The VE.Bus BMS V2 expands on that foundation with remote on/off, GX integration features, and enhanced safety controls to deliver greater flexibility and reliability in modern Victron installations.
