FAQ

Can Power Queen 48V lithium iron phosphate batteries be used as starter batteries?

No. The 48V battery is a high-voltage power source used for energy-intensive applications such as home energy storage and solar systems. Power Queen's 48V batteries are reliable.

What is the difference between 48V and 51.2V LiFePO4 batteries?

The 51.2V LiFePO4 battery is a powerful battery type intended as a replacement for lead-acid batteries.

To align with industry terminology, our 51.2V LiFePO4 battery is commonly referred to as a "48V" battery. Many customers and applications have long used 48V lead-acid batteries, so maintaining this nomenclature simplifies understanding and compatibility.

Technically, the battery's nominal voltage is 51.2 V, which corresponds to the actual output voltage of lithium iron phosphate (LiFePO4) cells, each operating at 3.2 V. Customers familiar with older 48 V systems can easily switch to lithium technology by retaining the "48 V" label and enjoying the benefits of higher capacity, longer lifespan, and more consistent performance without any compatibility issues.

Even though our battery is marked "48V", you can be confident that it is designed for stronger and more efficient performance, making it a suitable replacement for conventional lead-acid systems in all 48V-compatible applications.

How to charge the Power Queen LiFePO4 48V lithium batteries?

Due to the different charging requirements compared to lead-acid batteries, we recommend using a LiFePO4 lithium battery charger for charging.

Here are the charging options for Power Queen 48V lithium batteries:

1) AC-DC lithium battery charger: Choose a charger with the correct charging voltage to safely charge the battery.

2) Solar panels: If you are using solar panels, make sure you connect a solar charge controller to safely charge the battery.

3) Alternator/Generator:

a. If your alternator or generator supports a DC output, you will need a DC-DC charger to connect the battery.

b. If your alternator or generator supports an AC output, use a compatible battery charger, as recommended in the product manual, to safely connect the battery and generator.

Can I use a 48V LiFePO4 battery with my solar power system?

Yes, these batteries are compatible with solar systems. To achieve the best performance, use an MPPT solar charge controller designed for lithium batteries to maximize charging efficiency.

How do I care for a 48V lithium battery?

To maintain a 48V lithium battery, keep it clean, avoid overcharging, and store it in a cool, dry place. Power Queen's 48V lithium batteries feature built-in protection for easy maintenance.
