I've never left a review in my life, but this battery is great. I bought the 50 ah for my Jon boat in wired it in. My switch Panel has a USB C output so I can charge phones, cameras, flashlights, etc... I've done many overnight camp trips with the battery using my lightbar, interior lights, and even ran a shrimping light for 5 hours. With all the use I've never had it drop under 13.3v.

It’s a well-known fact among Waterfowl Hunters, if you what to test the durability of something, take it duck hunting once. If you want to destroy it permanently take it twice. Your product survived two seasons and surpassed my expectations to say the least.In November of 2022, I purchased a Power Queen 50ah battery from Amazon. I bought it because it had generally positive reviews and it was within my modest budget at the time. When it arrived, I had no idea of the value of what I had just purchased. I specifically purchased the battery to power a trolling motor on a light kayak used for duck hunting.Please allow me to give you a brief rundown of what this battery has been subjected to:1. This battery has been completely submerged in water for hours on end.2. It has been well used for two entire ice-cold duck seasons in the backwaters of Michigan.3. It has survived hundreds of miles of being bounced around in the back of a truck bed as we drove down poorly maintained dirt roads.4. It powered a 50# thrust trolling motor as we explored miles of weed and grass choked pond and rivers.5. It has recovered a boat that was sunken and completely submerged in 5ft of water. (Fun Fact: An electric winch will work under water when connected to your battery.)To top all of this off, on the last day of the season of 2023-2024, I was driving on my way home when a fellow driver caught my attention to let me know something was wrong with the boat I was pulling on a trailer. After I pulled over, I couldn’t immediately find anything wrong with the boat or trailer. Then I stepped around the passenger side and there it was. My 50ah battery had fallen out of the boat and was being dragged down the road by the cable connections.It looked bad to say the least. The electrical connections were destroyed and the few strands of wiring from the positive terminal were the only thing holding on to the battery. To say I was upset would be an understatement of a lifetime. There was nothing I could do except to collect my battery and finish my trip home. After I got home, I put everything away and made a plan to take the battery to the recycler.Last night, in my shop, I walked past the battery and gave it a good look. It was battered and covered in road rash but on closer observation it looked mostly intact. I decided to try to plug it in to the charger and see what happened. To my absolute surprise, it was still working! A quick check with multimeter confirmed it! It was still working just as well as it did the day I bought it.The case has been compromised and this particular battery will probably not be used on the water again but it will be replace with a Power Queen for sure. I’m impressed with the durability and construction of this battery. It has taken more abuse than it was made for and it just keeps working.

I got two more today and they checked out to be in good shape. I been using Power Queen for 3 years now and have 1000Ah at 24vdc for the main house and 600 Ah at 12Vdc on my backup radio and computer room. I don't have a big enough inverter to run the electric hot water heater and clothes dryer but the rest of the house runs off a solar panel system with Power Queen as the battery backup. The grid power is used to charge the batteries when there is no sun for several days. The grid continually goes down here a few days a month and sometimes up to 12 days with no grid power. So nice to have power for up to 3 days off the batteries. The small 600Ah system runs my Ham radios, internet, servers and computers 24/7. Washington state is into my grid power bill for $35.50 a month to support the climatic change hoax. I been using solar panel systems for nearly 40 yrs, none of them have lasted long enough to pay for themselves over grid power but it makes a nice backup when you live out in the woods. With Power Queen LiFePO4 batteries I think these will last long enough to pay for themselves.

Did the capacity test and it pulled more than 103amh. There probably a bit more left, but my inverter was giving me the low voltage warning. I stopped there. Didn't test the max amp, it handled 70amp no problem. It's a good basic battery at a great price.

Just installed and is coupled to my Go Power 3000 Watt Inverter in my small Travel Trailer. I had previously had a Stark Power 12V100AH battery that was installed in 2016 (Still going strong) and wanted to upgrade to a larger size along with getting the battery for $430 with the discounts (I bought the Stark Power one for $1100 back in 2016) this was a no brainer for me. Install was a breeze as I had sized everything in 2016 to accomodate a larger battery bank when costs came down. The Charge was at 13.2 VDC out of the box ~70% if I recall what their booklet showed. First thing I did was fire up the AC to see if it would run and it did with ease, I have a 13.5K BTU Dometic without soft start and the Powerqueen/Go power combo fired it up quickly, barely even noticed that first crank of the compressor it was so quick. I shut the AC off and then popped a batch of popcorn (1440W old school presto poplite air popper), worked like a champ, aside from the cheaper prices, the popcorn machine was the main reason for the upgrade ;), nothing like a fresh batch of popcorn popped in the middle of nowhere without having to fire a generator up. I have this battery coupled with 300 watts of solar on a MS Prostar MPPT-25 charger, I expect this battery to be well above my needs and to have enough buffer that I'm not worried about having a generator on hand to charge it. I am not planning to run the AC on the battery as I figure it would only run 1.5 hours to 2 hours at most and the battery would be exhausted. If the performance and life is anything like I have experienced with the Stark Power 12V100AH LIPO4, then I will be literally a Happy Camper. Will update down the road.
