The Victron VE.Bus BMS V2 for Victron LiFePO4 Batteries 12-48VDC is an advanced Battery Management System designed for VE.Bus inverters/inverter-chargers and GX devices. It protects one or multiple LiFePO4 Smart batteries and expands integration beyond the original BMS with remote on/off and GX features.
-
Voltage range: 12–48 VDC to work with Victron LiFePO4 smart batteries (12.8 V and 25.6 V variants).
-
Full cell monitoring: continuously monitors cell voltages and temperatures to protect each cell from over voltage, under voltage, and temperature extremes.
-
Pre‑alarm signaling: early warning of imminent under‑voltage conditions for 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.
-
Auxiliary power for GX: ensures the GX device remains powered even when the main system is shut down.
-
Multi‑device control: supports operation from multiple devices, including the Digital Multi Control, VE.Bus Smart dongle, and GX devices.
-
Compatibility: designed to work with all VE.Bus & GX devices for seamless integration.
By continuously monitoring cell voltages and temperatures, the VE.Bus BMS V2 protects each cell and the overall LiFePO4 battery system, helping extend battery life and prevent damage. The pre‑alarm feature provides early warnings, while automatic load, inverter, and charging controls prevent unsafe conditions. Remote on/off, GX integration, and multi‑device support offer flexible, centralized management across your Victron lithium setup, ensuring safe operation and reliable interoperability with VE.Bus inverters, inverter/chargers, and GX devices.
