Victron Energy SmallBMS NG Battery Management System for Lithium NG Batteries

SmallBMS NG

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 dont require integration with Victron inverter/chargers. It provides essential lithium battery protection without the added complexity of VE.Bus communication is therefore 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 theres 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.

Features:

• 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.

The Victron Energy SmallBMS NG is an efficient, all-in-one Battery Management System (BMS) specifically designed for Victron Lithium NG batteries. It offers essential battery protection and monitoring features suitable for 12V, 24V, and 48V systems, supporting configurations of series, parallel, or a combination of both. With a maximum capacity of 50 batteries in 12V or 24V banks and 25 batteries in 48V banks, it can manage up to 192 kWh, 384 kWh, and 128 kWh respectively, making it suitable for a variety of energy storage applications. The system’s compatibility with multiple batteries and its ability to expand capacity through parallel units provide flexibility for different project sizes.

Built-in Bluetooth connectivity allows direct communication with all lithium NG batteries in the system for central monitoring via the VictronConnect app. It receives real-time current and state of charge data directly from the batteries, eliminating the need for separate SmartShunt devices. This streamlined setup simplifies battery management and ensures accurate, real-time system insights. The SmallBMS NG features load and charge disconnect outputs, enabling remote control of external devices such as inverters, chargers, and load protectors. These outputs help prevent overdischarge and overvoltage conditions, safeguarding battery health and extending system lifespan. Pre-alarm outputs provide early warnings for low battery voltage, allowing users to take preventative measures before critical disconnections occur.

Additional features include remote on/off control for both load and charge disconnect outputs, LED indicators for Bluetooth status and error alerts, and a compact design suitable for various installation environments. The system is not compatible with lithium smart batteries or VE.Bus inverter/chargers, making it a straightforward and cost-effective solution for applications requiring essential lithium battery protection without complex integration. For detailed instructions and support, users are encouraged to consult the owner’s manual available online. The Victron Energy SmallBMS NG provides robust, reliable battery management tailored for lithium NG batteries, ensuring safe and efficient energy storage management in diverse applications.

Features:

• Load disconnect output controls remote on/off for connected loads to prevent deep discharge.

• Charge disconnect output manages remote on/off for chargers to avoid overvoltage conditions.

• Pre-alarm output provides early warning signals for low battery voltage to prevent system shutdowns.

• Remote on/off control allows external management of load and charge disconnect functions.

• LED indicators include a blue Bluetooth status light and a red warning/error indicator for quick system assessment.
