The SmallBMS NG is an all in one battery management system (BMS) designed for Victron Lithium NG batteries (Not compatible with lithium smart batteries).
It monitors and protects the batteries by managing charge and load disconnects and providing pre alarms for low battery voltage
The SmallBMS NG is a straightforward and cost-effective alternative to the VE.Bus BMS NG for applications that don’t require integration with Victron inverter/chargers. It is not suitable for use with VE.Bus inverter/chargers such as MultiPlus and Quattro.
With built-in Bluetooth, it connects directly to all lithium NG batteries in the system for central monitoring via VictronConnect. It also receives current and state of charge data directly from the batteries, so there’s no need for a separate SmartShunt.
The lithium NG batteries can be configured in series, parallel, or a combination of both, supporting 12V, 24V, and 48V systems. A maximum of 50 batteries can be used in 12V or 24V banks, and 25 batteries in 48V banks, enabling up to 192 kWh (12V), 384 kWh (24V), and 128 kWh (48V) of storage. Multiple Lynx Smart BMS units can be paralleled to expand capacity and ensure redundancy.
Key Features:
- Bluetooth Smart: The VE.Bus BMS NG includes Bluetooth Smart for wireless configuration, monitoring, and firmware updates via the VictronConnect App. Instant Readout shows key data such as SoC, battery temperature, warnings, and alarms directly in the device list, without needing to connect.
- Load disconnect output: Controls the remote on/off input of a BatteryProtect, inverter, DC-DC converter, or other loads with remote on/off functionality to prevent deep discharge.
- Charge disconnect output: Controls the remote on/off port of chargers such as the Smart IP43 Charger, a Cyrix-Li-Charge relay, a Cyrix-Li-ct Battery Combiner, or a BatteryProtect, to prevent overvoltage.
- Pre-alarm output: Provides early warning for low battery voltage before disconnecting loads. Can drive a relay, LED, or buzzer.
- Remote on/off control: Allows external control of both load and charge disconnect outputs.
- LED indicators: Includes a blue LED for Bluetooth status and a red LED for warnings and errors.
