Yes, LiFePO4 is an inherently safe chemistry and is recognized as the most stable lithium battery type on the market. Power Queen lithium cells are UL certified, ensuring they meet the highest standards for safety and sustainability. All Power Queen LiFePO4 batteries are 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, thereby safeguarding the battery cells from damage. Furthermore, Power Queen LiFePO4 lithium batteries have undergone rigorous testing to ensure they are free from the risks of fire and electric shock, even in harsh environments.

No, Power Queen LiFePO4 lithium batteries are designed solely for energy storage and should not be used as starting batteries. Please do not use them to start any devices.

For more information on the differences between these two types of batteries, read our blog post: "Deep Cycle vs. Starting Battery."

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.

Yes, you can charge Power Queen LiFePO4 lithium batteries with solar panels. Here are 3 reliable ways to charge

1. Using Solar Panels

The Power Queen 24V 100Ah battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 800W solar panels. It may take more than one day to fully charge the battery by ≥800W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.

2. Generator/Alternator

If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations.

The Recommended Charging Voltage: 28.4V - 29.2V. The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

3. LiFePO4 Smart Chargers

To charge 24V battery, it is recommended to use 29.2V battery charger.

The Recommended Charging Voltage: 28.4V - 29.2V.

The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
