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

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.

Best trolling motor battery I’ve ever owned. 1.5 years and working great 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!

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.

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

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.

I would like to say, first off if a low temp disconnect is a must have, move on. I believe Chins or Ampertime in their Smart versions have a heating wrap that goes around the cells and heats to >50F. For people with MPPT chargers that have a low temp sensor read on. I have had these batteries for about a month now. My kids use one in their cave " A fifth wheel they like to hang out in and play video games". We have 2 of these batteries in parallel with a waize pure sine wave inverter. They have allowed them to game away every night and they are recharged by 3pm. So, far zero issues even down to some low temps in Northern AZ. We keep our batteries indoors to prevent them from freezing. Never charge a frozen cell, you will destroy it. I will raise my review to 5 stars after 6 months of daily use and no problem.

I plan to update this review once I have had a chance to try the new system out while boon-docking, that is the reason for the rating on battery life and Longevity. At this point I have no reason to believe they are any better or worse then the manufactures claims. I bought 3 of the 100Ah Batteries as a replacement for my Travel Trailer batteries. The old 2 100Ah batteries were lead acid and they worked with a 2000 Watt inverter that I had installed. Due to a lack of low temp charging protection and the idea of theft I have moved these batteries into the front compartment. As space saving measurement I welded an aluminum cage and painted it black to hold all the batteries in a side by side vertical configuration. . These battery take up a lot less room once installed on their side standing up. This is a major advantage over lead acid (a lot more flexibility in installation options for small spaces.). I wired the 3 batteries in parallel to create a 300Ah 12v battery pack using 2/0 welding wire which should handle the 200 AMP's I have rated the system for. I then ran the wire to the roof the of the compartment and secured them with conduit straps (2/0 wire is pretty thick). From there I ran the wires over to a custom board I have mounted a positive and neutral 250 AMP buses bars. With a RV battery disconnect, a battery shunt and a 200 AMP breaker. I am really excited to go boon docking in 2 months and try this system out. I also plan in the mean time if I can make it work to hook up a battery Capacity tester to check out the actual battery pack capacity under a load. I will update once done.

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

Great so far
