【3.84kWh USABLE ENERGY & LONGER PERFORMANCE】A full charge on Power Queen 12.8V 300Ah LiFePO4 Battery can support 3.84kWh energy for 90% appliances, like running a 200W heater mat nonstop for 19 hours in winter. This lithium battery has a great 300Ah capacity with a low self-discharge rate, the depth of discharge of our battery is about 100%, which provide 40% more usable power than the 300Ah lead-acid battery. If you want a satisfied big power, this battery would be your best choice!
【200A BMS WITH 2560W MAX. LOAD POWER】Power Queen 300Ah Lithium Battery has built-in 200A BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit. Our battery has 12 cells inside, the auto motive grade cells are high-density and stable, it’s safe when used in our daily life and friendly for the environment. And 2.56kW Max. Load Power would allow us to connect more common applications simultaneously to enjoy a more convenient life.
【DOUBLE STORAGE CAPACITY FOR THE SAME FOOTPRINT】If you were planning on being off-grid quite a bit, installed lead-acid batteries just weren’t enough. Because the lead-acid battery is too heavy to move. And it can only discharge 60% of energy when you use multi applications. Our 12.8V 300Ah LiFePO4 battery has more than double storage capacity for the same footprint compared with a lead-acid battery. Our 12.8V 300Ah Lithium Battery is a great replacement of lead-acid battery!
【MAX. 61.44kWh ENERGY STORAGE SOLUTIONS】Power Queen 12.8V 300Ah LiFePO4 Batteries support up to 4 in parallel and 4 in series (Max. 4P4S) to get more capacity (600Ah, 900Ah, Max.1200Ah) and higher voltage (25.6V, 38.4V, Max.51.2V). Max connected in 16 batteries (Max. 4P4S) to get a 51.2V 1200Ah battery system, with 61.44kWh energy. This powerful storage solution could be widely used for the home solar system, emergency backup power system, and yachts trip.
【Warm Tips】① This Battery is an energy storage battery rather than a start-up battery, we do not advise using it to start engines or golf carts. ② If OT terminals are attached directly with screws and their thickness is less than 2mm, please add gaskets to ensure secure attachment and prevent loosening or overheating. The same precaution applies when using clamps

Solid reliable batteries.
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.

Amazing!
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 donât 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 donât 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 acidâs 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, itâs still a win in my opinion. They cost less, thereâs less maintenance, more performance, no acid leaking and are very easy to maneuver in the event I need to use them with an inverter.

Good customer service
Love these batteries,never had an issue while using it for solar, the design is great with the terminals at one end. They are heavy so we built a extra duty shelf for them. Great value for the money. Good customer service when you contact them with questions.

Great Batteries for Mobility Scooters
I got these batteries to replace the SLA batteries in my mobility scooter. They are exactly the same size and amp hrs ratings and are less than half the weight! I got the LiFePo4 charger and they last almost twice as long and charge in less than half the time!! Better performance, longer run time and less weight makes the switch to LiFePo4 batteries the best choice! The life expectancy (recharge cycles) are rated more than 10 times more! So, YES, I recommend the Power Queen LiFePo4 batteries to anyone looking to replace their SLA deep cycle batteries.

I bought two batteries both used discribed as good quality.The first battery was perfect looking like new and tested good for a charge.The second battery arrived Dead and obvious signs of wear . After contacting the seller ie Powerqueen and following the instructions received to get the battery to wake up the battery still remained dead . After a follow up a return label was issued. After the item was recieved back in the wearhouse.A replacement battery was shipped and both batteries have been balanced and being now run in parallel.The customer support was although not as fast as I would have liked now saying that it was excellent.My frustrations where purely down to the 12 hr time difference between the Battery manufacturers and my location.1.Am I happy with the BatteriesYes2.Am I happy with Customer Support.Yes .3. Would I buy anotherToday’s Answer is YesDepending on the longgivety of my current ones .To conclude Buy with Confidence.A Good Battery at a Good Price with Customer service all be it in a different time zone. Be patient and give them time to address your issues.

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

Purchased this battery, to upgrade my AGM set up in the RV, can’t get over how light the battery is. Charges quickly and holds its voltage right down to the bottom. Best purchase I have ever made for an upgrade to the RV, wish I had swapped over to lithium a long time ago.****** now about customer service, I live in a very rural and there was a problem with the shipper. Bella called from China, to help and resolve the issue, went well out her way to assist me in locating the battery. I can not recommend this company enough, have never experienced this level of customer service from any vendor, they have a lifelong customer.I have now purchased 2 of these units, and have them in my RV, They work fanantastic. even with the furnace running they, recharge so quickly and the voltage doesn’t drop like AGM batteries.Best decision I ever made.
