Power Queen 12V 300Ah LiFePO4 Battery, 3840Wh Lithium Battery with 2560W Power Output, Up to 15000+ Deep Cycles, BMS Protections for Solar, RV Motorhome, Marine, Off-Grid

This battery is as described with no obvious defects. The warranty is six years, and the expected useful life is ten years If all goes well, I will purchase a second battery. Then install a solar system to achieve moderate energy independence.. I purchased a 12V 100Ah Power Queen battery for my trolling motor last October, the product has provided reliable performance since its purchase, so The 200AH battery is purchased with great confidence.

Replaced an older lead acid battery with voltage averaging 11.8 volts. The Power Queen averaged 13.0 ALL day. Recharged quickly also. Plus much less weight. I’ll be looking into Power Queen for trolling motor battery replacement next year. Great price. I don’t make my living fishing it’s just fun. I didn’t break the bank buying this. The app works great also for monitoring the battery.

Working good so far.

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!

It's on the large side but not very heavy and stored pawer is plentiful. I install it on my 2025 Cherokee gray wolf 25rrt and I'm very happy with it.

It’s only been a week of using it, and I’m using it for my trolling motor but so far it’s worked great. The Bluetooth app is very simple and user friendly and the battery life seems to be great

Easy to install, weighs less

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.

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

Great so far
