Victron VE.Bus BMS - BMS300200000

Victron Energy VE.Bus BMS – Battery Management System for LiFePO₄ Batteries (BMS300200000)

The VE.Bus BMS by Victron Energy is a dedicated battery management system for Victron's Lithium Iron Phosphate (LiFePO₄) batteries equipped with BTV (Balancing, Temperature and Voltage control). It protects individual cells from damage by monitoring voltage and temperature, and it performs automated load and charge disconnection based on real-time battery conditions. Ideal for both mobile and stationary applications, it ensures safe and reliable system operation across a range of voltages.

Key Features

• Protects individual battery cells from over-voltage, under-voltage, and over-temperature
• Compatible with 12V, 24V, and 48V Victron LiFePO₄ systems
• Works with VE.Bus inverter/chargers (MultiPlus, Quattro, Phoenix) via RJ45
• Three logic-level control outputs: Load Disconnect, Charge Disconnect, Pre-alarm
• Supports daisy-chained BTV connections across multiple batteries
• Small form factor, ideal for boats, vehicles, and off-grid power systems
