When purchasing, pay close attention to the energy capacity (Wh), nominal voltage/capacity, charge/discharge temperature range, and BMS (Battery Management System) functions. The energy value determines the total energy storage capacity; 1280Wh can support the basic electricity needs of an average household for several hours. The nominal voltage must match the inverter or electrical equipment. A wider charge/discharge temperature range allows for a wider range of applicable scenarios. The overvoltage/overcurrent protection and equalization charging functions of the intelligent BMS directly affect battery life. If long-term off-grid use is required, it is recommended to choose a model that supports low-temperature discharge (below -20°C) and confirm that the discharge cutoff voltage meets the equipment requirements.
