Victron Energy SmallBMS (Smart & NG, with Pre-Alarm)

SmallBMS with pre-alarm

Ideal for Victron Smart LiFePO₄ smart batteries with M8 circular connectors, the SmallBMS replaces the VE.Bus BMS V2 in stand-alone systems. It features:

• Dual outputs for charge and load disconnect to prevent overvoltage and deep discharge

• Pre-alarm functionality to trigger external relays, LEDs, or buzzers before shutdown

• Simple integration—no VE.Bus interface needed, plug directly into Smart LiFePO₄ batteries

SmallBMS NG

Engineered exclusively for Victron Lithium NG batteries (not compatible with lithium smart batteries), the SmallBMS NG elevates protection and monitoring:

• Built-in Bluetooth & VictronConnect support—centralize monitoring and receive current & state-of-charge data directly (no SmartShunt required)

• Charge & load disconnect outputs with remote on/off control for chargers, inverters, DC-DC converters, and other loads

• Pre-alarm output for early warning of low battery voltage

• Scalable architecture—supports 12 V, 24 V, and 48 V systems: up to 50 batteries per 12 V/24 V bank (192 kWh/384 kWh) or 25 batteries per 48 V bank (128 kWh)

• Pre-alarm output and LED indicators to show Bluetooth status and system warnings
