I have to say that I wasn't expecting much when I bought them. I thought, at least I'll get some prismatic cells out of them and then replace the BMS with a better one. But I waited a year before I left this review. I built a solar generator as my gas generator never sarts every time lights go out. (My fault: bad owner) But I decided to connect my fridge for 1 year just to keep the batteries cycling. These batteries have never failed. Always provide power to have some comfort after the storms. I have Weize 1200w inverter, only consumes 4 watts on idle, and 6 - 100 watt Eco Worthy panels and Sunthysis 40 amp charge controller that keeps my batteries top off. Even after 6 days straight of storms and cloudy days, the batteries never died. 2-3 days of sun later, and they are topped off again. I like the fact that I know I can leave for a week and trust my fridge will always be powered.

Served it's purpose, held up well. I connected 2 in series for a 24v system. They stayed mostly in tune without a balancer, as long as you follow the correct instructions. You charge each one independently full, let it stabilize, then connect them, let them stabilize, then charge them together, a lead on one negative and one positive til full. Then stabilize again before use, check with meter how they are charged up to and balanced. Then use properly connected in your system. I take no responsibility for your use or misuse, or improper connections. Follow a pro somewhere at your own discretion somewhere else. I recommend some YouTube videos, DIY solar forums and maybe better educated in this field in some areas guides, like Will P. Look him up. They provide some good instructions, fairly easy to to hook up together. Mine came with two sets of lugs to swap out depending your needs I believe. M8 and M10. Batteries held capacity, ran as needed and got then while on sale at the time at a great value for use. They don't have Bluetooth or anything built in unfortunately and I needed higher capacity, so I upgraded, yet they were still at right capacity as new. Figure out your needs and maybe buy higher to start, or ones like this are a grwat starting point to learn about lifepo4 Lithium batteries. Practice safety, cover terminals and don't arc, tighten properly and follow safety precautions for safety and use. Make sure to check connections often. Always turn off solar panels first, use switch for correct V and capacity and turn off, as well as inverter, before working on and any other safety factors I didn't mention. These were stable batteries for me and were worth it at the time. Worked well, including the BMS usually. Pay attention to max discharge and charge rate though, it does provide some limitations. If you keep realistic and don't have too high of needs at once, then these will work well overall. Get what works for you too.

Use: Battery swap and UPGRADE for 36v gold cart Quantity: 3 Weight: -22lbs each! (For a total of 66lbs) -I switched from 6 Interstate lead acid (55lbs each totaling 330lbs) losing 264lbs from the cart and it certainly feels it! Charger: -Updated to an on board charger (15amp Noco Genius "Gen5x3") -I keep it connected to my batteries and simply plug it in when I'm done using the cart. It charges each battery individually and stops charging individually as well. -I'd go bigger maybe 20amp or 30amp if you want a fast charge. It works well, but it did take aprox 14-16 hours to charge them back to full after the trip mentioned below. Practical test: -On 07/12 the wife and I took the cart out on a date night The new batteries on a full charge read right at 42v on the voltage meter. -That night we drove 24.2 miles over the course of 4 hours averaging 14mph with LED headlights ON -When we got home and they read at 39.1v PARTS USED FOR BUILD: 3 of these batteries- $187.99 each 1 Noco Genius "Gen5x3" $187.99 1 Pair of 8in wires (golf cart wires)-$12 1 Pair of 14in wires (golf cart wires)- $14 2 Longer terminal bolts(aprox 1.25in)- had'em 1 Master kill switch- $13 -This helps make sure not of my accessories aren't leaching my batteries -IMPORTANT: Using this became the connection point from the far end of the sequenced battery + side to the positive cable coming directly from the cart (I would have had to buy a very long cable, one and then connected them with a creative solution) GET the SWITCH. GRAND TOTAL for swap: $790.96 NOTES: -The bolts (Phillips head) that the batteries come with are pretty short but worked for all the terminals that were minimally occupied (battery charger &battery charger and cable). -I had to use some longer ones on the terminals that I tied my accessories into OPINION: I was extremely skeptical making the switch and opening the money. I could find but 1 other review that did this swap, it was very helpful Do the swap! If your hesitant it's understandable but these are less expensive (overall), light in weight (your cart will go faster) have better longevity and can run for longer periods. I believe the batters would have kept running after the trip mentions above. I am so glad I did! For the money the outperform lead acid, save a ton of weight on the cart and should last 3-5x times as along!

the quality of these will surprise you. very lite and easy to install. with the right charger they don't take long at all to charge. Such a great design and function well under a load.

I am a 79 year old retired engineer. I live in a rural area on Lake of the Ozarks where my 2002 EZGO electric golf cart is the major way of moving around the property. I had a need to replace my old worn out lead acid, deep cycle batteries after 6 years. Looking at the alternatives, lead acid Vs Lithium. The lead acid batteries are a constant pain needing water. Lithium is almost maintenance free. Lithium batteries weigh about a fourth of lead acid, and deliver just as much power. I lost 300lbs of weight on my cart that makes it faster. Lithium batteries charge faster. Lead acid can be charged 500 to 1,000 times. Lithium 2,000 to 5,000 times. The only negative I see is in the winter that 300lbs of extra weight helps in snow, but I am 79, and try not to get out in the snow DON'T make my mistake. Initially be sure to fully charge each Battery separate, and place them 24hrs in parallel. This will require a 12v Lithium Battery charger. I had a 36v lithium charger, but did not have a 12v lithium charger, and had a problem with the batteries being balanced, and my cart would just die when one of the three batteries went low. My batteries were reading: First battery (Neg load side) 12.82v, Middle battery 7.92v, Third battery 13.31v . Since then I bought a 12v charger with lithium capabilities, and fully charged all three batteries, and put them in parallel for 24 hrs. They all had a 14.2v reading after putting them in series for my 36v EZGO TXT 36v electric. So far no new problem. I believe this fixed my problem. Also, avoid disrupting the voltage balance of the 36V 100AH ​​battery pack by, for example, do not draw 12V power from one of the 12V 100AH batteries. Buy a step down transformer to get 12v, or use a seperate 12v battery

DEFECTIVE PRODUCT THAT DOES NOT LAST 2 YEARS AND SELLER DOES NOT HONOR THE 10 YEAR WARRANTY! THEY WORKED GREAT FOR JUST UNDER 2 YEARS BUT THEY WILL NOT HONOR THEIR ADVERTISED WARRANTY! DO NOT REMEND THIS PRODUCT AS ADVERTISED!

I needed to replace the battery in my boat I use to run my 12 inch UHD2 Garmin unit and Livescope. I have a friend who had bought this battery in a lower amp hour version and has gotten great use from it so far. I read its specifications and it seemed to be a well made battery. The price was equal to a lead acid battery instead of being the jacked up price of a pure lithium. I knew I would have to buy a battery charger either way so I ordered it. I have been using it for 3 weeks, running the 12" Uhd2, Livescope "black box" and a 9" unit. I start off my mornings showing from 13.4 -13.6 volts and after 8 hours of fishing still show from 12.9-13.1 volts and according to the charge lights on the battery case it is still at 3/4 charge. My livescope is showing up much better / brighter. So far I am thoroughly pleased with this investment. The paperwork with the battery said it could be charged over 4,000 times and should last 10 years. If it does, and I'm still able to get around then - I'll be buying another just like it.

Very good Batterys but if you put them in a golf cart for 36 V, you have to put a balancer on all three batteries cause overtime. One battery will eventually die. They do not stay balance on a 36 V golf cart.
