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

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!

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.

Great battery plenty of power

Update: Went out on the Waccasassa River yesterday and completed a full day of fishing and travel totalling 14 miles--10 miles of river travel and 4 miles of maneuvering and exploring small offshoot creeks. There was a medium tide all day working against me both ways and I was able to get 4.3 mph on full speed 5/5, 3.1 mph on cruise speed 3/5. Most of the time I used speeds 2-4 with speed 3 being the primary speed. On the way back home upriver I used speeds 4 and 5 because of the head current. I switched batteries at 9 miles. The first battery began to weaken a small bit around 8.5 miles but showed 12.8v still. I was able to run on full speed for about .5 miles at a time before the battery would reset, and then turn back on almost instantly. I shifted to speed 4 for a few minutes, then back to speed 5 for another .5 miles until the battery reset again. When I reached the launch at the end of the day battery 2 had 13.1 volts left and was able to operate with full power still. My two previous brand new 67 pound 120ah size 31 lead acid batteries would be totally depleted or dead if I had taken such a trip before, limiting my ability to cover lots of water. I ended up buying the Power Queen 10a charger because the small Noco 2a one was too slow to charge them. It charges them in about 6 hours from 12.8v to full. I will update after several more trips. Original Review: My first Lithium Batteries ever, and first impression was theyre so light and seem very well made. I had two 120ah 31 size batteries for my canoe that weigh 124 pounds, and these cant be but about 20lbs per battery. My back isnt what it used to be so even if performance is similar, the weight savings easily makes up for the investment. Lifting them was such a surprise...effortlessly in and out of the car and canoe. Ill be going fishing this weekend and will be doing a video on how they work and how long they last using my 55lb Newport Vessels motor and various accessories...Helix 5 FF, Livewell pump, full nav lights and led lightbar. Ill also update this review over a period of six months to help guide folks along if its for them or not. Also, in my canoe they mount on a slight angle which is not so great for lead acid batteries, but no problem at all for these which can be mounted practically any way you want. I also added a Noco 2 amp onboard charger and will update on how well and how fast it charges them after a day on the water.

Easy to install, weighs less

These batteries are much smaller and lighter than the Lead-Acid batteries. This make a big difference for me on my small aluminum boat. They can also be placed in any configuration, so this means that I can actually put the battery in my boat compartments. They are more expensive for sure, but provide better flexibility on my boat.

This little battery surpassed my expectations (and I never say that for anything coming out of China). It has survived a real winter of -30c and colder, has always put out full power and hasnt let us down. Although one thing to watch out for: charging at 14.4v will cause the bms to spike up to 16v when its fully charged. Repeating this over time WILL destroy the battery. The fix: use solar for recharging (unless you watch your AC charger like a hawk) and set the absorb voltage to 14.1 or lower. Aside from that, I can recommend it even for the winter months, just dont freeze it.

Après l’avoir essayé plusieurs fois cette année, je l’a recommande fortement. Très légère et dure très longtemps lors de mes journées de pêche. Je suis très satisfait de mon achat. Merci

From the videos I saw youtube, it is well build and meets its power characteristics. Documentation is good, too, battery comes with a comprehensive booklet. All good, but I would think it applies to most LifePO4 batteries, they are probably made from pretty much the same cells and electronic controllers. But what seams to be the strong point of Power Queen is their customer service. There is a facebook group run by Power Queen were you can address issues or ask specific questions and it is most likely that they will reply if you don't get an answer from other members . Also, Power Queen reached out to me to find out if I received the battery and wanted to know I was happy with my purchase. So, I am very confident I will get a good service if an issue should occur.

Arrived before due date. Very happy about that. It has charged up fine with the battery charger I bought. I will update this once I try it even though I'm a little nervous about using it with my trolling motor, but it says it should be fine
