Awesome battery. Solved problems of traditional battery used in Ford Fusion Energy where car designer tried treating like a solar battery. No more battery failures. It took Ford technicians to explain car doesn’t use traditional alternator to recharge battery. This worked as simple drop in replacement without needing extra parts. Exceeded their expectations and should last 10 years instead of 2. No issues with computer errors.

Great battery!! It fits perfectly between the support pillars in the center hatch of my PA14 kayak. Very light weight. I was running a Garmin 93sv and a livescope 34 on it for 5 hours and it only dropped .2 percent. Should easily last a couple full days of fishing and then some maybe!

I was skeptical buying the cheapest LiFePO4 on amazon. Story time: I had the battery for about two months before installed it in my 21' toy hauler and immediately went camping. First night no issue. Second night the battery cut off power completely. I was bummed. The next morning, I unhook the battery for 30+ minutes as instructed in the manual and it came back to life. It charged off my solar all day, but this is winter and the panels were not clean nor in optimal sun. I saw 175 watts of peak charge for probably 1.5 hours. I didn't think much of it. Third night, the battery cut off again, be it a little later in the evening. I was pretty upset with myself for never learning my lesson about being cheap. And not realizing we don't have real camping gear like flash lights because the trailer always works and has power... Well previously it did with two deep cycle 6v in series for "200ah" of which you are only supposed to discharge to 50%. Those batteries don't just shut off at 50%... they will let you drain as far as you want. Needless to say I was wondering how to get away from this battery and back to buying lead acid every 3 years. After sending an email to power queen support and getting a response within 24 hours (on the weekend), they told me they thought the battery was under charged. I emailed back and said I don't think so. That is was showing 13.3v after the all day solar charge. They wanted be to charge it using a dedicated LiFePO4 charger and even offered to send me one to borrow. I purchased Ardroit 14.6V 30A LifePO4 Battery Charger from here on amazon and promptly charged the battery overnight. After using the charger, I again saw 13.35 volts on my "AiLi Voltmeter Ammeter" battery monitor. I reset the battery monitor for 200ah and 100% charge. I was ready to prove Selena and Power Queen wrong and get my money back ( as the offered) if the battery did not meet 200ah. I turned on various loads in the trailer. Had three heating pads (12a total) going for a while. Turned on all the lights, though LED so not a ton of current. Bathroom fan, switched the fridge on, etc. I wanted to test it as I would used it camping and maybe a little more. I shut my solar off and left for work with a load that would vary from 4-14 amps depending on what was turning on and off. In total I tested the battery for 36 hours without charging it. I tested like I would use it. I was wrong about this battery under performing. The battery monitor showed that at least 200ah worth of energy had passed thought the shunt. This battery well outperformed my lead acids. I was shocked about the responsiveness and help from the customer service Queen Selena. Noe seriously, very helpful and nice... not condescending, like the basically non existent customer service found at any other company I recall in the last 10 years. I didn't realize how high the battery voltage stays on this battery throughout usage. At only 32% battery life left on the monitor, this battery still had 13.03v. The high voltage I saw out camping after the solar charge was probably just a "surface charge". There is no way my 450w solar setup, in under preforming conditions, fully recharged the battery. I'm tell you all this, incase you find your self testing this battery for the first time out camping... and you start to question the sanity of your purchase. I suggest either purchasing a dedicated LiFePO4 charger, or let your solar, charge the battery for a week (depending on conditions) before you are relying on it 100%. Get a battery monitory. The cheap one I mentioned above is great... you don't need a $200 victron bla bla bla. Relying on only voltage to tell state of charge, may get you in trouble as it did me. Now that I have schooled myself the hard way... I love this battery. I cannot yet speak for longevity of this product, but they state a 5 year warranty. If this company is around in 5 years, they will honor it judging by how they handled me. I suspect they will be around as more people take the chance on this "no name" battery and are pleasantly surprised by it. I recommend this battery and this company.

This battery exceeded my expectation with its light weight and ability to run my trolling motor or fish-finder as long as I’m on the water.

[UPDATE 09/18/25]: I was skeptical about the capacity of this 50 Ah battery, but after putting it through a few cycles, it actually has a capacity of about 57 Ah! It charges at 17 Amps, but never gets to 14.4 V while on the charger. It delivers 13.4V until about 80% capacity, then it starts to drop off. It keeps my Starlink Mini happily powered through the 20V cigarette lighter booster until the BMS cuts power. [Original]: I'm on the fence about this battery, I have a Power Queen 100 Ah LiFePO4 battery and have tested its capacity several times over the 1+ years I've owned it. Using my charger, the 100 Ah battery charges to a maximum of 14.4 V (as expected) at 17 amps before my charger considers it full. This 50 Ah battery shows full when the battery reaches 13.4 V and only charges at a little over 5 Amps using the same smart charger. I haven't tested its capacity yet, as I'm in the process of running until the battery monitoring system shuts it down at it's cut-off voltage. When that's done I'll recharge it and measure how many amp-hours get put back into it.

Efficient power for my electric trolling motor. My canoe can go 12 hours at 10 amps which yields 3mph. Light weight compared to my lead acid battery. Expensive at first but expecting maybe 10 years of life which makes it very economical.
