Yes, LiFePO4 is an inherently safe chemistry and is considered the most stable lithium battery type on the market. Power Queen lithium cells are UL certified, meeting the highest standards for safety and sustainability. Each Power Queen LiFePO4 battery comes equipped with an internal Battery Management System (BMS) that offers protection against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during both charge and discharge, and short circuits, safeguarding the battery cells. Additionally, Power Queen LiFePO4 lithium batteries have been rigorously tested to ensure they are free from the risk of fire and electric shock, even in harsh environments.

No, Power Queen LiFePO4 lithium batteries are specifically designed for energy storage and are not suitable for use as starting batteries. Avoid using them to start any devices.

Yes. Power Queen 12V deep cycle lithium batteries can be connected 4 in series to create a 48V battery system.

Note: DO NOT connect batteries with different chemistries in sereis or parallel.

The 12V series batteries offer flexible connection options, including series, parallel, and series-parallel configurations. You can connect up to four 12V 300Ah batteries in series, four in parallel, or up to sixteen in a series-parallel setup, achieving a total capacity of 40.96 kW and 61.44 kWh of energy.

Ensure that batteries of the same model and similar capacity are used for these configurations.

It is recommended to store Power Queen LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10℃～35℃ (50℉～95℉), 45%RH～75％RH.
