VE.Bus BMS NG — is a next-generation management system from Victron Energy, designed for Lithium NG (LiFePO₄) series lithium batteries. It provides automatic protection, monitoring, and control of charging and discharging in systems that include Victron inverters and inverter-chargers with a VE.Bus interface. The system is capable of handling large battery banks, supporting up to 50 batteries in 12/24 V configurations and up to 25 batteries in 48 V configurations.
Key features and benefits:
- Battery protection against overvoltage, deep discharge, overheating/overcooling
- VE.Bus integration – support for MultiPlus, Quattro, EasySolar, and more.
- Bluetooth Smart – wireless configuration, firmware updates, battery status monitoring in VictronConnect
- Direct measurement of SoC (state of charge), current, and voltage without the need for a SmartShunt
- Support for scalable systems – up to 192 kWh of energy for 12 V, up to 384 kWh for 24 V, up to 128 kWh for 48 V
Digital outputs and interfaces:
- Load Disconnect – load disconnection in case of dangerous cell voltage (up to 1 A)
- Charge Disconnect – disconnects charging in case of overvoltage or excessive temperatures
- Pre-alarm – low voltage warning 30 seconds before load disconnection
- Remote On/Off – remote system on/off
- 2x RJ45 VE.Bus ports – connection to inverters/chargers
- GX-Power port – power supply for GX devices (e.g., Cerbo GX)
Technical Specifications:
- Input Voltage: 9 – 70 V DC
- Current Consumption: 10 mA in normal mode, 2 mA at reduced voltage
- Temperature range: –20 °C … +50 °C
- Housing material: ABS, color – matte black with a blue sticker
- Protection: IP20
- Dimensions: 23.2 × 95.0 × 105.8 mm
- Weight: 120 g
Compatibility:
- Victron inverters and inverter chargers with VE.Bus
- Cerbo GX, GX Touch, and Digital Multi Control monitoring devices
- Victron Lithium NG batteries (12.8 V, 25.6 V, 51.2 V)
- External relays, BatteryProtect, Cyrix, other Victron controllers
Typical application scenarios:
- Off-grid power stations with high-capacity batteries
- Integrated solar systems with MultiPlus / Quattro inverters
- Industrial, commercial, private, and mobile power systems
