I ordered two batteries and they arrived earlier than anticipated. Out of the box, the starting voltage was about 3.2 volts per battery. Initially I had an issue getting my charger to recognize the batteries and begin charging despite the charger supposedly having a minimal starting voltage of 2v. I had to hook up a solar panel to bring the voltage up a bit and the charger worked no problem. You may have to use a manual charger for a bit if you don’t have a solar panel. I purchased these batteries to run a 24v Clarke auto scrubber. I picked this battery in particular because of the 500amp max starting voltage. Once I wired the batteries up in series to get up to 24 volts per battery I used my scrubber to clean 10,000sqft and it was a flawless experience. The batteries performed perfectly and were actually a bit smaller than the four 6v lead acid batteries they replaced and weighed a fraction of them too. Another bonus was that the voltage remained constant (above 13v per battery) and did not fade in power output like traditional led acid batteries tend to do. By the end of the cleaning, battery temp was relatively cool, around 82 degrees Fahrenheit. Another great feature is the Bluetooth capability. It allows you to monitor each battery in real time for pretty much every thing you need to know while under load: voltage, amperage, watts, temperature, remaining amp hours and estimated time remaining. It does the opposite when charging and gives you an estimated time to when the batteries will be charged - fantastic. Another perk is never having to worry about adding water ever again. In fact, you don’t have any of the concerns with these Power Queen batteries that you do with lead acid batteries since they are lithium iron phosphate. My last point comes to the value you get for your money: these cost less than buying four 6v lead acid batteries and will last thousands of cycles(supposedly 6,000) vs lead acid’s hundreds. You will occasionally need to charge each battery individually to make sure they are both equalized. Even if these batteries only last me 4 years, it’s still a win in my opinion. They cost less, there’s less maintenance, more performance, no acid leaking and are very easy to maneuver in the event I need to use them with an inverter.

Very good customer service and they have a great battery. I purchased 3 of the 50 ah for my Jon boat and they are light and have worked flawless so far!

This battery is nice. It lasts way longer on my trolling motor than I expected. It’s not heavy and seems well made. Time will tell on durability but so far no issues.

I have 3 of these in parallel for almost 8kw of power in my rv. Charging using 2000 watts of solar and victron controllers. They perform great and run my rv completely off grid 24/7, I also have a 12k btu mini split it runs no problem all night.

I bought three of the 100ah 12 volt power queen batteries for my RV. They worked for one cycle and then died and will not charge with my lithium 12 volt charger. Too late to return, so that’s $700 down the drain.Update 02.10.2025: PowerQueen offered me a full refund for these batteries but I thought I’d give their recommended charger a try first to see if my 3 battery bank could be brought back to life, and it worked! Yay! It did take 37 hours for this depleted 3 battery bank to be brought back to life. Hope this info helps anyone with similar issues.

This review is for both the 12.8 volt 200 AH Plus LiFePO4 and the 12.8 volt 410 AH LiFePO4 batteries.Two years ago I bought the 12.8 volt 200 AH Plus LiFePO4 battery, and have heavily used this battery with zero issues. That battery was only 40 lbs, and it replaced two very heavy 6 volt Trojan batteries.Lead acid batteries are heavy, need water added, and the gas from charging corrodes terminals and is very explosive hydrogen gas. Lithium eliminates all of that.We live in our 5th wheel RV full time. We use a 600 watt solar array on the roof to keep the 12 volt system charged, leaving the "house" 12 volt converter/charger off. That 12 volt charger uses quite a bit of 120 volt current, since we pay for our electricity from the meter, using the solar array helps on the electric bill. This set up really shines while out boondocking.It is a self built hybrid system. There is an added 120 volt receptacle in our kitchen wired to a 2200 watt inverter. We use this solar provided power daily for grinding and making coffee, and also for the toaster. There is also a 500 watt inverter that runs our TV and the cellular internet gizmo. I like the fact that we can leave the TV on all day without cost.Plus of course the 12 volt lights, furnace and fans. While it is possible, we do not run the A/C from the solar array. We use 120 volt shore power for our A/C, refrigerator and hot water heater use.The Power Queen 200 AH battery has performed flawlessly these last two years of constant use. I had a fuse issue while we were away from the RV for a period of time 2 months ago, a fuse blew, turning off the array. The battery was stone dead, but recovered without issue with my solar charger once the fuse was replaced.In the last year battery prices have gone down quite a bit, so this last January 2025 I bought the 12.8 volt 410 AH LiFePO4 as an upgrade to my system. As with the first battery I bought from Power Queen, the delivery was fast with next day service. It is the size of an 8D battery and weighs an amazing 80 lbs. It is well strapped down and secure.I cannot comment on support service from Power Queen as both batteries have been issue free.But both times I bought a battery from Power Queen, I received an email, a sort of checking in to make sure I received the battery and please let us know if you have an issue. I even got a phone call on my first battery purchase, while appreciated, I do not speak Chinese and the English was nil.Reviews are important for my buying decisions, and the reviews reported for Power Queen lithium batteries were instrumental in my purchase.I would buy another battery from Power Queen without hesitation.
Very good product

I charged and recharged it 3 times and it is functioning normally. I ordered 2 other batteries from this company after purchasing this specific battery because it worked great and they work well too! . I was very happy about the constant updates about the shipping.

we veronderstellen dat hij goed is, want hij is nu ingebouwd in de camper, maar de camper staat stil deze maand . Maar zo te zien, zijn we tevreden

Battery so far it's living up to the expectations. Charged it for the first use and lasted multiple hours and then some compared to my previously 2 lead acid batteries. Very lightweight and easy to install. Highly recommended lithium battery

The weight savings alone is crazy...I used one of these to replace the 2 group 31 agm deep cycle marine batteries in my boat. With 2 lead acid batteries id get about 8 to 10 hours on the water using the trolling motor, stereo, 2 fish finders and charge ports, before my low voltage warning alarm would sound.With this new battery i spent 12 hours + on a windy day fishing with 2 of us in the boat, and still had 40% battery power left.☆☆☆☆☆
