These batteries can be connected in series<\/strong>, in parallel<\/strong>or in a series\/parallel combination<\/strong>. Thanks to this flexibility, it is possible to form battery banks that work with system voltages of 12V, 24V or 48V<\/strong>.<\/p>\n In a 12V or 24V system, up to 50 batteries<\/strong>. This allows for a maximum energy storage of 192 kWh<\/strong> at 12V and 384 kWh<\/strong> at 24V. For 48V systems, on the other hand, the limit is 25 batteries<\/strong>which provides up to 128 kWh<\/strong> capacity.<\/p>\n The SmallBMS NG offers a simple and cost-effective alternative<\/strong> to the model VE.Bus BMS NG<\/strong>. Provides basic protection<\/strong> for lithium batteries without the need for VE.Bus communication. However, it is not compatible with VE.Bus inverters or chargers, such as the models MultiPlus<\/strong> y Quattro<\/strong>.<\/p>\n The SmallBMS NG includes Bluetooth Smart connectivity, allowing it to be configured, monitored and firmware updated wirelessly via the VictronConnect app.<\/p>\n This output allows you to control the remote on\/off function of devices such as: This prevents deep discharge of the battery. It can also be used to activate a high current relay<\/strong> or a contactor<\/strong>although in some cases it is necessary to inverter\/non-inverter cable.<\/strong> For further details, it is recommended to consult the product manual.<\/p>\n This output controls the remote on\/off switching of: It is not recommended to use this output to supply inductive loads such as relay coils. Its function is only to enable or disable the remote power port.<\/p>\n It provides key data such as: This information is displayed directly in the device list, without the need for additional connection.<\/p>\n The pre-alarm output activates a visual or audible warning when the battery voltage level is low. This occurs at least 30 seconds before<\/strong> the load output is switched off due to undervoltage. Allows both outputs of the system to be controlled remotely. When this input is switched off, both outputs are inactive. This interrupts the operation of the connected chargers and loads.<\/p>\n Protects the battery by setting a minimum charge level (SoC), preventing deep discharge and ensuring sufficient power to maintain essential functions. When the charge level approaches the limit, VictronConnect displays a warning and triggers a pre-alarm. If the critical threshold is reached, the system issues an alarm and automatically disconnects connected loads, preserving battery health and extending battery life.<\/p>\n The Victron smallBMS NG - BMS400100300 features two LED indicators that provide clear and quick information about the system status. A blue LED signals Bluetooth connection activity and status, while a red LED warns of errors or alarm situations, facilitating efficient, real-time monitoring.<\/p>\nFeatures of the Victron SmallBMS NG - BMS400100300:<\/h2>\n
