Power Queen 12V 100Ah LiFePO4 BMS Battery Review

(Last Updated On: May 10, 2023)

Deep cycle batteries are an excellent alternative for power stations because you can get a ton of capacity for a fraction of the cost. Of course, you also have to factor in how you will use the battery, which will likely be an inverter; however, adding in an inverter will most likely keep the cost way down compared to purchasing a power station.

This review looks at this Power Queen 12V 100Ah LiFePO4 deep cycle battery. This is very similar, practically the same type of battery I’ve reviewed from REDODO and Ampere TIme (now Li Time), so let’s see if it meets the same standards.

What Comes in the Box?

In the box with the Power Queen battery, you’ll get four post bolts, a negative and positive rubber cap, the manual, and a paper mentioning important notes. The battery does not come with a charger, so you have to purchase that separately. Overall, what’s included in the box is on par with other brands.

Power Capacity

To figure out the capacity of this Power Queen battery, you have to multiply the voltage of 12.8V by the Amp Hours, which is 100Ah, which means this Power Queen battery has a 1280Wh battery capacity. This is a lot of power, but what matters most is how much of the 1280Wh you can use. That is why I ran a capacity efficiency test using a load tester. I had the load tester running at about 120W continuously until the Power Queen battery reached 0%; the test ran for nearly 11 hours, and I could pull 1268Wh, which gave me about 99% efficiency from the battery.

When doing a direct battery capacity efficiency test, 100% or near 100% is expected, and this Power Queen battery meets expectations.

Another capacity test I ran was via an inverter, with the battery charged up to 100%; I used an ALFFAA 1500W inverter to run a heater on high continuously. In this case, I used a watt meter to see how much power I could pull from the battery through an inverter. I ran the heater until the battery was at 0%, and I ended up with a 1,100Wh capacity, which gives me about an 85% efficiency rating. In this case, the Power Queen battery efficiency is lower because the power has gone through the inverter, so some power is lost. That said, an AC capacity efficiency of 85% is better than most power stations.

So you can use most of the 1280Wh capacity, and how long you can use the battery depends on what you plan on powering from it. A heater pulling about 800W would last approximately 1.5 hours with the battery, while a 1200W heater would last about an hour only.

Also, I almost forgot to mention that this is a Lithium Iron Phosphate (LiFePO4) battery, so it can go 3,000 charge cycles and maintain 80%+ of its efficiency. These types of deep-cycle batteries are the way to go because of LiFePO4, and even power stations have started to use LiFePO4 battery cells, too.

Output Power

The power output of this Power Queen 1280Wh battery is, well, 1280W. For testing, I used an ALFFAA 1500W Pure Sine Wave inverter to power appliances from this Power Queen battery. However, there are many other ways to use deep-cycle batteries, such as this one.

Connecting the ALFFAA inverter was easy by connecting the positive and negative terminal cables to each end of the battery and the inverter itself. Once connected, the inverter turned on, and I was ready to power appliances.

As I mentioned, the first appliance that I tested was a heater. First, I set the heater to low and then to high. At low, the heater pulled about 800W, then at its high setting, it pulled 1350W. Even though the Power Queen is rated to output 1280W, the battery kept supplying power to the ALFFAA inverter.

The other appliance I powered was an electric cooktop, and I filled up a saucepan with four cups of water set the cooktop to higher, which pulled about 850W, and after about 8 minutes, the water began boiling. Of course, I expected the battery and the inverter to power the cooktop easily, considering that it could power the heater continuously at 1350W.

Size and Weight

This Power Queen battery has a 13-inch length, a 6-inch width, and an 8-inch height. The battery weighs 24 pounds. So basically the same as most other 100Ah LiFePO4 batteries. The weight is the part you will mostly feel, as the battery itself isn’t very large.

Conclusion

This is a great competitor, along with REDODO and Li Time batteries, as the battery capacity efficiency and wattage output worked how they’re supposed and sometimes surpassed expectations.
