Power Queen 12V 100Ah LiFePO4 Battery, Group 31 Lithium Battery with 1280Wh Energy and BMS Protection, Up to 15000 Deep Cycles for RV Trailer, Solar Off-Grid, Marine

Man Where do I start. This seller personally called me to check on my purchase (it may have been in broken english from an Asian lady but damn, that’s service). I was honestly flying blind on whether three 12.8v batteries wired in series would mess up my 36v golf cart but for the last two weeks it hasn’t caused a single problem. Make note that if you’re replacing a ton of 6volt batteries in your golf cart that the bracket under them (or at least on my EZGo) doesn’t match up for a longer battery. The batteries are super light. The value for the money is 100% there. The battery life is insane. Okay, I know it’s rigged up in my picture, deal with it! I have to get the bracket cut and welded to fit, once I get that done I’ll clean up the wires and make it pretty under there. As for longevity- I bought that meter because I wasn’t sure if the stock one in my golf cart would work with these batteries. It didn’t drop below 100% and I’m not really sure if that’s due to the nature of how these batteries supply 100% of their power and then just die (which they haven’t done yet)… but… my kids have driven the golf cart around for 4+ days in a row without charging them once. With the previous batteries we had to charge them after each partial days use. Not much else to report on. They work awesome and this seller is awesome. Update - The batteries have died after 4 days of use in the golf cart. I have contacted the seller and will update the review accordingly as the process progresses!

Lite and very strong

I've been relying on this battery for a few weeks now of fishing. And it works well. Charges fast and I've been through thick grass and pushed my trolling motor to the limits and it just keeps giving power. I'm not exactly sure yet how much run time I have on the water. Longest I've spent is 6hrs of fishing relying on this battery as a main power source and it'll usually take 3hrs to charge after use or that long. So I'd say if you're powering a 55lb thrust trolling motor you'd could be good for at least 8hrs of fishing but probably towards 10hrs. I'm having to use the fastest setting most of the time through grass and its held up great. I'll update my review if I run into any errors but so far it's been a great battery for an angler who powers their vessel with a trolling motor.

I like this battery allot. I bought a 100ah class 31. I used only my trolling motor. To go up and back 3 times on a lake this fall. Each trip was roughly 2 miles. I'm sure i could have made 3 more. I'm an amazed at the power this battery has. Not to mention how light it is. I have arthritis in my shoulders. I can pick this battery up without an issue. In messaging with Power Queen shortly after buying this class 31. I was astonished when the rep said that the Class 24 100ah battery will last as long as a Class 31 100ah battery. That really doesn't compute to me. The Class 31 is what nearly 4 inches longer then a Class 24. Idk i guess it's like what weighs more, a ton of bricks or a ton of feathers? I don't know, b4 I buy my next battery. I will need to verify that statement. Either way I'm sold on Lifepo4 by Power Queen. My only concern is the bolts 6mm bolt with 13mm head. I hook up 3 or 4 wire lugs. I haven't cross threaded it yet. It does feel like it wouldn't be hard to do. I might look into an "Adapter kit" one that i can bolt down on the positive and negative with a more durable connection on the other end. Something exactly like on a SLA battery only different.

I bought one of these 12v/100Ah batteries back in March of 2022 to try it out with my solar system on my truck. Results were on point... So, I purchased the 12v/200Ah in May of 2022 to put in my toy hauler. Once again, result were great. Since then, I have purchased 4 more batteries for a total of 6. Another 12v/200Ah and 3 more 12v/100Ah batteries... And they are all still going strong. I have 2 x 200Ah wired in parallel, running a 2000W inverter on one system and 2 x 100Ah wired in parallel running a 1500W inverter on a stand alone system all installed in my toy hauler. I have 2 x 100Ah wired in parallel installed in my truck camper running a 2000W inverter which I use frequently. I only issue I have had out of the 6 batteries, is one of them swelled up a little during charging and stayed swollen. Not bad, but enough to notice. Regardless, it still performs without any problem. Yes, I know you can get some swelling while charging. Anyway, as long as it continues to perform, it's not an issue for me. I highly recommend this seller as well as these batteries for off-grid/deep-cycle configurations. And customer support is off the charts. They actually called me to make sure the batteries were performing to my expectations. Granted, there are plenty of identical clones of these batteries out there and customer support usually sets them apart.

Been using this battery for almost 1 year now. 12.8v 100ah using Noco charger to charge it. This is the best battery for marine electronics. It powers my trolling motor, Livescope, and 2 garmin graphs, plus lighting on my boat. I start the day at 6am with 13.2v and I keep my electronics on all day plus always on my trolling motor at 70 speed (I suck at fishing and can’t find fish). When I leave the lake at 6pm my graphs tell me the battery is at 13.0-13.1. I would say this battery could easily last 3 full long days on one charge. Product came in great packaging with lots of accessories that I didn’t know I wanted or needed. The posts come with caps and have multiple placements. They also don’t corrode at all.

Easy to install, weighs less

I have 3 of these on my sailboat and they work great. Build quality is solid, performance is as expected. Tested at 102 AH from full charge

Just as good as a Daktoa for a fraction of the price

Great so far
