Yes, LiFePO4 (Lithium Iron Phosphate) is one of the safest and most stable types of lithium batteries available on the market. Power Queen lithium cells are UL certified, adhering to the highest standards for safety and sustainability. Each Power Queen LiFePO4 battery features an internal Battery Management System (BMS) that provides comprehensive protection against various risks. These include under-voltage during discharge, over-voltage during charging, over-current during discharge, over-temperature during both charging and discharging, and short-circuit events, ensuring the battery cells remain undamaged. Moreover, Power Queen LiFePO4 batteries have been rigorously tested and found to be free from fire hazards and electric shock risks, even in challenging environments.

No. Power Queen LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

For further details, please consult the "Deep Cycle VS Starting Battery" article.

The Power Queen 12V 50Ah Deep Cycle Lithium Batteries can be safely charged within a temperature range of 32°F to 113°F (0°C to 45°C). However, charging below freezing temperatures can potentially damage the battery cells.

For optimal storage of Power Queen LiFePO4 batteries, it is recommended to keep them at a 50% state of charge (SOC). If the batteries will be stored for an extended period, it is advisable to cycle them at least once every six months. Recommended storage environment: 10℃～35℃ (50℉～95℉), 45%RH～75％RH.

The Power Queen 12V 50Ah Deep Cycle Lithium Battery has a maximum continuous discharge of 50Ah and a peak discharge of 100Ah for 5 seconds.
