It monitors and protects the batteries against over voltage and under voltage of any individual cell, and also over temperature or under temperature conditions.\u003c\/p\u003e\u003cp\u003eWith built-in Bluetooth, the BMS provides central monitoring via VictronConnect. The BMS derives all key parameters including voltage, current, state of charge and individual cell data directly from the battery, removing the 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.\u003c\/p\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003ch4 style=\"margin:16px 0 6px 0;\"\u003eKey
