I highly recommend this battery and heard about it from the guy shown on the Amazon listing for this product. It has a 5 year warranty, and good cells, and smaller size. The BMS is what puts this into the excellent category. Not only is it a high quality BMS, it has Bluetooth support so you know how well balanced the 4 cells are to each other. I found that cell matching with closely matched voltages are very important. The only thing I wish they would change is to make the bolts another 1/4 inch longer (the bolts are 3/8" long), but if you use a MRBF fuse, it may not be a problem. It is also very easy to purchase longer bolts, but after adding a washer and a split lock washer you likely only have room for one lug. I highly recommend this battery.

This battery is quality made and even the battery case is well made and durable. It’s a 24 volt and easy to install. It came with an extra set of terminals. I bought it to use to power my trolling motor for my boat to replace the 2, 12 volt batteries I had. So far, it has worked great. Delivery was fast and on time.

I did a lot of research within the field of LIFEPo4 batteries in hopes of finding a good replacement set for my 10 year old golf cart lead acid batteries for my off grid cabin. No need to maintain individual cells with distilled water, light weight at about 24 pounds, much improved recharge depth, and on board Battery Management logic were all big pluses for me. There sure were a lot of lithium iron phosphate batteries out there to consider all in the 12 volt 100 amp hour category using the same form factor of 4 cells, a BMS monitor, and a bluetooth interface for monitoring on your smartphone. I did research a few YouTube reviews and tried to find the right price point for durability and features that I needed. I settled on Elefast a product of FEENCE a big name in the manufacturing of Lithium batteries. I ordered an initial 3 from an AMAZON vendor knowing I could return them if it did not work out. I received them a few days after placing the order. They were nicely packed in boxes well protected in styrofoam with a plastic liner covering the top and terminals. I used a voltmeter to test the charge of each battery. they were all 13.1 volts at about 50% charged. I downloaded the recommended smartphone app but did not care much for that one. Instead I searched on Google Play and downloaded another free one named Overkill Solar that I liked a lot. It immediately recognized my batteries via Bluetooth on my smartphone. The app had an edit feature so I could uniquely rename each battery so I could isolate each one's performance characteristics. My first test was to bring all three batteries up to 100% full charge which I did using a LIFEPo4 enabled charger that charged at about 9.1 amps. Took about 4 hours to bring each battery from about 50% charge to 100% and the BMS worked perfectly to stop the charging when full. Then I started a decharge test but it took so long to decharge I focused only on one of the batteries and brought it back down to 50%. I did not yet have them hooked up in parallel as an array so I was happy at how long running a 40 watt light took to decharge one battery. With a partial test completed, I charged the one battery back to full. I let them sit for a week and my BMS app shows them still at 100% full. I am ready to install them in place as soon as the weather cools a bit to get up to my off grid location. About 6 100 watt solar panels and a Trace C40 controller will keep them charged and in float mode while I am away. I was so impressed by the batteries that I bought a 4th to ensure that I will have sufficient amp hours in storage to run my fridge, lights, stereo and TV for a few days off the grid. The only thing that I could not find any answer for was the advertiser stated that these batteries were 1 cell when they clearly have 4 separate cells as indicated by case size and BMS reporting. So far not an issue there. So as it stands I recommend the Elefast LIFEpo4 battery for off grid and RV living. Only time will tell if the longevity lives up to the marketing statements.

Shipping came earlier than expected! It is so much lighter than our bother batteries. Bass boat trolling motor approved!! My husband is very happy!

Great capacity. Trolled 3 days with MK Power Drive 70lb motor and only used about 25 amps. I should've bought the 50 amp battery.

Good value. Unfortunately after 8 months I had problem with battery not taking a charge. Keven from customer support was very communicative and helped me troubleshoot, but ultimately I needed the battery exchanged under warranty. Thank you!

I bought two of these and despite some issues with the BMS they seemed to work well enough, so I bought a third one. The third one only charges to 80% as reported by the iOS app. I put in for a return because I couldn't see any way to contact the seller for support, but they contacted me about the return and were able to resolve the issue. It turns out that the iOS app only provides limited functionality unless you login and even then they have to grant you additional permission to your specific account. I removed one star for that. I bought the product, I shouldn't need an account or to ask for special permission to get the full use of the product I paid for. But anyway, the third battery was delivered with the cells very badly out of balance, limiting capacity, but I was able to balance the cells and now it seems to be fine. I haven't done a precision capacity test, but the numbers reported by the iOS app seem reasonable.
