Victron VE.Bus BMS V2 - BMS300200200

Overview

The Victron VE.Bus BMS V2 is a Battery Management System designed to protect and manage Victron Lithium Battery Smart 12.8 V and 25.6 V (LiFePO₄) batteries in systems that use Victron VE.Bus inverters or inverter/chargers. It continuously monitors individual cell voltage and battery temperature to ensure safe and reliable system operation.

When abnormal conditions are detected, the VE.Bus BMS V2 intelligently controls charging, discharging, and system loads to prevent battery damage. It is the next-generation solution for VE.Bus-based lithium systems, offering expanded functionality and deeper integration with the Victron ecosystem.

Key Features

Comprehensive Battery Protection

• Monitors individual cell over-voltage and under-voltage
• Protects against over-temperature and under-temperature conditions
• Ensures long-term lithium battery health and safety

Intelligent System Control

• Generates a pre-alarm signal for imminent cell under-voltage
• Disables inverter operation via VE.Bus during critical conditions
• Disconnects loads using the Load Disconnect terminal when required
• Disables charging via VE.Bus and Charge Disconnect terminal during unsafe conditions

Next-Generation VE.Bus BMS V2 Enhancements

• Remote on/off terminals for system-level control
• Ability to disable VE.Direct and VE.Can solar chargers via a GX device
• Allows multiple control interfaces such as Digital Multi Control, VE.Bus Smart Dongle, and GX devices
• Auxiliary power input and output to keep a GX device powered during system shutdown

Flexible System Integration

• Supports single or multiple Victron Lithium Battery Smart modules
• Suitable for 12 V, 24 V, and higher voltage VE.Bus systems
• Designed for systems with or without a GX device
