Victron Energy VE.Bus BMS V2 – LiFePO4 Smart battery management system – BMS300200200

VE.Bus BMS V2 BMS300200200 – is Victron’s LiFePO4 Smart battery management system, which protects batteries from overcharging, deep discharge, overheating, and excessive current. The BMS monitors each battery via built-in Bluetooth or the VE.Can/VE.Bus bus, sends commands to inverters, chargers, and protection devices (BatteryProtect), and provides automatic integration with Cerbo GX / Ekrano GX / VRM.

Key benefits of the VE.Bus BMS V2 battery management system

1. Smart LiFePO4 lithium battery protection – voltage, temperature, and balance monitoring.
2. Full integration with VE.Bus devices – MultiPlus, Quattro, MultiPlus-II, Quattro-II
3. Automatic charging and load on/off – based on signals from the batteries.
4.  Support for up to 5 different inputs/outputs – including GX devices.
5. Compatibility with Victron Smart BatteryProtect – centralized load shutdown.
6. Support for intelligent charge control (DVCC) – precise current and voltage regulation.
7.  Compact DIN-rail mountable housing – ideal for electrical panels.
