Victron VE.Bus BMS NG Battery Management System [BMS300200300]
The Victron VE.Bus BMS NG is a smart battery management system built for Victron Lithium NG batteries in systems with VE.Bus inverters or inverter/chargers. It protects against overvoltage, undervoltage, and temperature issues across individual cells. With Bluetooth connectivity, it pulls data directly from batteries for easy monitoring via the VictronConnect app—no extra shunt required. You can scale up to 50 batteries for massive storage, making it ideal for reliable power in marine or off-grid setups. It ensures your system runs safely and efficiently, cutting downtime risks.
Key Features
- Monitors cell voltage and temperature to prevent overvoltage, undervoltage, or extreme temps
- Built-in Bluetooth for wireless setup, monitoring, and updates through VictronConnect app
- Shows instant readout of state of charge, battery temp, warnings, and alarms
- Load disconnect output controls BatteryProtect, inverters, or other loads to avoid deep discharge
- Charge disconnect output manages chargers like Smart IP43 or Cyrix-Li relays to stop overvoltage
- Pre-alarm output gives early alerts for low voltage via relay, LED, or buzzer
- Remote on/off lets you control load and charge outputs externally
- LED indicators: blue for Bluetooth status, red for warnings and errors
- Supports series, parallel, or mixed configs for 12V, 24V, 48V systems
- Handles up to 50 batteries in 12V/24V banks or 25 in 48V for high-capacity storage
Perfect For
- Marine vessels needing reliable battery protection in VE.Bus systems
- Off-grid solar setups with Victron inverters for expanded energy storage
- RV electrical systems requiring Bluetooth monitoring and easy scaling
- Backup power banks in remote locations with multiple Lithium NG batteries
- Systems aiming for redundancy by paralleling multiple BMS units
