VICTRON ENERGY smallBMS NG Battery Management System – BMS400100300

Description

VICTRON ENERGY smallBMS NG Battery Management System – BMS400100300

The Victron Energy smallBMS NG is an all-in-one battery management system designed specifically for Victron Lithium NG batteries. It provides essential lithium battery protection by managing charge disconnect, load disconnect, and low-voltage pre-alarm functions, while also offering built-in Bluetooth monitoring through the VictronConnect app. This compact BMS is a straightforward option for 12V, 24V, and 48V Lithium NG systems that do not require VE.Bus inverter/charger integration.

• Designed for Victron Lithium NG batteries in 12V, 24V, and 48V systems
• Load disconnect output helps protect the battery bank from deep discharge
• Charge disconnect output helps protect the battery bank from overvoltage
• Pre-alarm output provides early warning before low-voltage load disconnect
• Built-in Bluetooth enables centralized monitoring through VictronConnect

The smallBMS NG is intended for systems without VE.Bus inverter/chargers. For systems using Victron MultiPlus or Quattro inverter/chargers, a VE.Bus BMS NG or other suitable Victron BMS should be selected instead.
