FAQ

Q: Are Power Queen LiFePO4 Lithium batteries safe?

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.

Q: Can I use Power Queen LiFePO4 Lithium batteries as starting batteries?

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.

Q: Can I charge Power Queen LiFePO4 lithium batteries in cold weather (under freezing temperatures)?

The Power Queen 12V 50Ah Deep Cycle Lithium Batteries can be safely charged within a temperature range of 32℉ to 122℉ (0℃ to 50℃). However, charging below freezing temperatures can potentially damage the battery cells.

Q: How do I store Power Queen LiFePO4 lithium batteries?

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.

For more detailed, you can read the article: Storing LiFePO4 Batteries: A Guide to Proper Storage.

Q: What is the maximum discharge capacity of a Power Queen 12V 50Ah Deep Cycle Lithium Battery?

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.

Q: What is the lifespan of the Power Queen 12V 50Ah Deep Cycle Lithium Battery?

A Power Queen LiFePO4 lithium battery can be used for 4000-15000 life cycles, which can be 10 years or more depending on usage. Lead acid and AGM batteries have about 300-500 life cycles before their capacity is significantly reduced. Despite the higher initial cost, upgrading to a Power Queen LiFePO4 battery will save you a lot of money in the long run.

Q: How do I know what size the Power Queen LiFePO4 lithium battery I need?

The Power Queen LiFePO4 lithium battery has approximately twice the useful capacity of lead acid and AGM batteries. So, if you want longer useful battery time (Amps), you should upgrade to a battery of the same (or higher) Amps. For example, if you replace a 100amp battery with a Power Queen 12V 100Ah LiFePO4 Lithium Battery, you will obtain around twice as many useful amps while weighing half as much. If your goal is to have a battery that is smaller, lighter, and less expensive. Then, replace the 100amp battery with a Power Queen 12V 50Ah LiFePO4 Lithium Battery. You will receive roughly the same number of useful amps (time), but it will cost less and it's about 1/6 the weight.
