2.RV and Marine Applications: These batteries are perfect for powering lights, appliances, and electronic equipment in RVs, boats, and yachts, providing a dependable and long-lasting power source.

3.Off-Grid Power Solutions: LiFePO4 batteries are suitable for off-grid cabins, cottages, and distant sites where a consistent power supply is required.

4.Backup Power for Home and Business: During a power outage, they can provide backup power to homes, businesses, and vital systems.

5. UPS (Uninterruptible Power Supply): UPS systems can incorporate LiFePO4 batteries to offer dependable and long-lasting backup power for critical equipment.

Q: How to charge Power Queen 12V 280Ah lithium batteries?

1. Using Solar Panels

The Power Queen 12V 280Ah battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 1200W solar panels. It may take more than one day to fully charge the battery by ≥1200W 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: 14.2V - 14.6V. The Recommended Charging Current: ① 56A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 140A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

3. LiFePO4 Smart Chargers

To charge 12V battery, it is recommended to use 14.6V battery charger. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 56A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 140A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.Related reading: Can I Charge a Lifepo4 Battery With a Lead Acid Charger?

It would take around 12.3h to charge when using 12V 20A lithium battery charger and around 6.1h to charge when using 12V 40A lithium battery charger.

Q: Can I pair a Bluetooth Module for this battery to monitor the battery status on the phone?

No. This battery is not compatible with the Bluetooth module. You can use a 500A Battery Monitor With Shunt to keep track of battery status.

More details about battery monitor, you can read the article What Is A Battery Monitor.

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

LiFePO4 batteries may be securely charged at temperatures ranging from 32°F to 122°F (0°C to 50°C). The Power Queen 12V 280Ah LiFePO4 batteries provide low-temperature charging protection, which automatically stops charging when the cell temperature falls below 32°F, preventing harm to the battery cells during cold conditions.

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

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