FAQ

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

A: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.

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

A:LiFePO4 batteries can be safely charged within the temperature range of 32°F to 122°F (0°C to 50°C). The Power Queen 12V 280Ah LiFePO4 batteries feature low-temperature charging protection, which automatically halts charging when the cell temperature drops below 32°F, thereby preventing damage to the battery cells during charging in freezing conditions.

Q: How to charge Power Queen 12V 280Ah lithium batteries?
A: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 14h to charge when using 12V 20A lithium battery charger and around 7h to charge when using 12V 40A lithium battery charger.
