Wish I had found the light weight battery sooner. So far, no problems and it holds a good charge all day.

I’ve had so many issues with batteries in my boat, when the latest set died (2 years) I decided to try lithium. These were no more expensive than the lead acids I’ve been buying so if I even get half the quoted life (5 years) out of these it’s a deal.So yes I’ve only had them about a month but I’ve got some good testing in, multiple 12 hour fishing days (bass fishing), lowest I’ve got these batts is 68% capacity and no performance decrease by the end of the day. They seriously kick ass. But what’s really got me sold is the monitoring. Im so sick of feeling in the dark when “I swear they shouldn’t be this weak already” on the water and basically any other issue u can imagine.It already saved me once, finished fishing for the day and plugged the boat in at home, the charger showed one charging and one on fully charged, so I checked the battery app, one was at 89% and charging, the other was at 65% on STANDBY! Turned out my brand new noco pro 2 bank charger I bought at the same time as these batts was junk! Without the power queen monitor who knows when I would’ve figured that out since the batts will still read 13v even at a low charge. Anyway maybe they’ll crap out next year and I’ll update but if I’m very happy with them so far.

You might pay a tad more for PQ but I am here to tell you it is well worth it. This battery is well made as there are many Youtube tear down videos to prove it. I have a few of mine now going on 3 years and still perform flawlessly. TY PQ.

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.

ManWhere 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!

There are many brand-name LiFePo batteries on the market today, but I cannot imagine any better for value and customer support than Power Queen. These lightweight batteries live up to their specifications. They are powerful, reliable, and quick to recharge. And my communication with customer service has been prompt, courteous, and customer-oriented. You'll not find any better prices either - and keep an eye on them, they often have amazing sales. But now a note: If you're changing out a lead-acid for one of these LiFePO batteries in your RV, check to see if your onboard converter supports the new battery. New one's might, but older ones may only give you an 80% charge.

Light and economic.

This has been connected to the Backup Sump Pump in our basement as a replacement of the dead 12v 190ah Lead Acid battery that was there. Since receiving it, I fully charged it with a Lithium Charger and then connected it to the Backup System that is designed to charge Lead Acid. It has been floating at 99% for months now and is tested once a week to make sure it is in good running order. After about two months it hasn't even had a single full cycle. So I expect this battery to last a very long time with it's new purpose.
