I bought two of them two months ago and so far so good.. It's too early to tell but they do seem to run down pretty fast. I would think a hundred amp hour would have more storage.. I dunno.

BOUGHT BATTERY I 10/10/2024 WITH A ASURION MONTHLY WARRANTY. IT'S MARCH AND NOW IT'S FAILED, WON'T TAKE A CHARGE, HAS 0 VOLTS ON OHM METRE. TRIED TO PROCESS A CLAIM WITH ASURION AND THEIR SYSTEM HAD TO ENROLL THE ITEM 1ST. AND AT THE END OF THE CLAIM IT SAID TO CONTACT AN AGENT. I TRIED 4 TIMES WITH THE CHAT THING BUT IT KEPT LOGING MY OFF WHILE I WAS CHATTING. POOR PRODUCT, WORST SERVICE! BOUGHT 3 BATTERIES AT THE SAME TIME 2 FROM LITIME (WORKING GREAT!), ONE FROM FIUNIE! REGRET THE FIUNIE ONE!

Switched from lead acid, wow what a difference! Slightly more than traditional lead acid but so much better. Love that you can turn the batteries off and have an app for easy monitoring. Set up with solar system and works great!

This batteries are not charging when the weather is below 50 Degree Fahrenheit, am using Renogy 40amp Dc to Dc Charger and everything is set right, what can do to make them charge?

I have three fiunie lifpo4 batteries and all preform very well. Exceeded my expectations. I see now the offer them in a light grey color that will reduce the surface temperature when exposed to the sun in the john boat with a 50lb minn kota trolling motor I use them in. Can go 3.5 mph in setting 5 for 3-4 hrs per 100 amph battery drawing 26-28 amps. Really like the lighter weight and ability to use more of the capacity than a lead acid battery.

Love the ability to use their app to check battery status.

I bought this battery for about 2 weeks and has been testing it for about 1 1/2 weeks. So far it seems to hold the charge well. Did not try its Bluetooth yet. The BMS allows the battery to go 10volts before cut off. Because of that it would give more output than 1280wh. But if you limit your usage to ~1280wh, then the battery will stay above 10volt. By doing so will prolong the life of the battery. Other than that, it's a good battery.After 5 months, this battery failed. I suspect that these cell batteries are either used or low graded. I have been using the Renogy mppt solar charge controller (40A).

I needed to replace the batteries in our travel trailer, I decided it was a good time to move to LiFePO4. Although it is not strictly necessary, I chose to also upgrade my converter/charger to work with LiFePo4.Batteries I received were only about sixty days old and had an appropriate charge on them. Before installing I gave them a couple of cycles to improve the cell balancing and confirm initial capacity 102-104 AH each) I now have them installed in parallel to provide 200AH.To be honest, I felt like I gambled on these batteries because the price was so low. So far they have been flawless, and I later learned they have a very good BMS!Pros:- Same or smaller than standard batteries. I was able to fit two into the Camco double box with room to spare.-Excellent BMS and decent Bluetooth range. I can read batteries from about 75 feet- BMS is fully programmable and compatible with other apps (try the overkill solar app)- Manufacturer confirmed low temperature charging cutoff ( I have not confirmed myself).Cons:- BMS min and max cell voltages were aggressive, I dialed mine back.- BMS doesn't record battery cycles (mine are stuck at 1 cycle)- Percent remaining shown on the BMS is not accurate, but that seems to be true for all BMS. I would recommend using a shunt and tracking the ampere hours.- Manufacturers app was difficult to use. Good news is that 3rd party apps have been designed for this BMS!I wouldn't hesitate to buy these again or to recommend these to family and friends. For trailer batteries these are a perfect match for us, we just completed 4 days of boondocking and still had about 90 AH remaining!Final Note: Bluetooth is a little weird on this type of device as you don't actually pair with it. If you disconnect the app the battery will need 30-60 seconds to timeout before it becomes available for a new connection. Once I figured this out it worked much better :-)Update 11/12- finally got cold enough here to test the low temperature charge cutoff. It works! One thing to note in my test was that the BMS didn't open the MOSFET until there was a charge current. As soon as there was a charge current the BMS disabled charging! Still so impressed with these batteries.
