FAQ
Do I need a waterproof charger for this marine battery?
Yes. For best performance and safety, we recommend using a waterproof lithium-compatible charger when charging on a boat. This ensures safe charging in marine environments and protects your equipment from water damage.
In what applications can I use 12V 280Ah LiFePO4 lithium battery?
1.Solar Energy Storage: LiFePO4 batteries are widely used in off-grid solar energy systems to store and utilize electricity generated from solar panels.
2.RVs and Marine Applications: These batteries are suitable for powering lights, appliances, and electronic devices in RVs, boats, and yachts, offering a dependable and durable power solution.
3.Off-Grid Power Solutions: LiFePO4 batteries are ideal for off-grid cabins, cottages, or remote locations where reliable power supply is essential.
4.Backup Power for Home and Business: They can serve as backup power sources for homes, businesses, or critical systems during power outages.
5.UPS (Uninterruptible Power Supply): LiFePO4 batteries can be integrated into UPS systems to provide reliable and long-lasting backup power for essential equipment.
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.
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.
Can I charge Power Queen LiFePO4 lithium batteries in cold weather (under freezing temperatures)?
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.
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.
