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.

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.

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.

Quick delivery with good packaging. All shipped voltages were exactly the same. Roughly 30%soc. I charged them individually (ordered 4) With 20amp Lithium charger. Voltage between them varied within 125mv. (Took over 2 days to charge all of them) Had to charge 3 of them individually to get voltage the same to connect in series to a 5kw inverter charge controller. Discharged and charged for a few days from 100% to about 5% keeping track of AH with victron smart shunt. Voltages between batteries near the top of charge cycle and bottom of discharge cycle would drift a bit, 50 to 150mv but remained pretty close in the middle. Not sure what's going on but no magic smoke anywhere. During my last pull I was able to extract 199AH capacity with 5% still in the batteries+/- I'm sure it will pull more which is good, they hold what they claim so I'm satisfied except for the voltage variation I observed at high and low states of charge. Had them for a few weeks now, running them every day off of 2k of used solar powering a 6000btu ac in my work shed. Would have been 5 star if not for the odd voltage issue, which has diminished slightly over time but still mildly concerning. Time will tell, but over all I'm satisfied so far. 8/21/2024 9:56 PM EST - Just tried to order 4 more of these guys in some (LIGHTNING) sale for $399 a piece which is totally cool and a fantastic price but unfortunately for some reason the seller would only allow 1 piece in my cart. I thought about making 4 separate purchases but didn't know if it's a one shot deal. I can't use one battery, I need a set of 4. I'm kinda pissed off because I saw this deal, I checked my finances and I gave myself the ok to pull the trigger. I was excited about adding capacity to my system until I tried to increase the quantity in my cart. No option to do so. That sucks!
