This is my 2nd 12V 100Ah. Connected in parallel with a different 100Ah LiFePo4 and they work and charge as expected. The Bluetooth app is basic but it works well.

Converted old ezgo golf cart with three mini lithium batteries as the battery compartment could not accommodate one 36 volt battery due to size and layout. Reduced the weight of the cart by 300 pounds by eliminating the lead acid batteries. Cart has been through several charges and I am pleased with the performance so far. Cart is very quick. Manufacturer did not recommend the batteries for golf carts but should work well with 250 amp controllers. Have run the cart wide open for 2 miles straight with no issues. BMS is balancing the batteries well.

I got this and charged it full to 14.6v and then did a discharge test, so far so good. It is quite small for its capacity and seems to provide the advertised Wh. One issue I have is, the listing states the terminal size as M8 which = 5/16 so I sized my connectors as such. They are actually M6 on the battery I received. Not the end of the world but somewhat annoying and not what is advertised.
For those of you with concerns about the app, try the Overkill Solar app. It allows you to make adjustments like turning charging/discharging on and off etc. It has connected every time for me so far.
I’m up to 3 of these now for 3,840Wh in my DIY portable power station. Working well as of now.

The battery seemed to good for the price but after a few months of using it it went bad. Shows zero volts on the multi meter and won’t take a charge at all. Needless to say to say the Bluetooth feature would not connect either, so there’s no type of diagnostics available. I messaged the seller twice with no response. So it’s a gamble to purchase since the “5 year guarantee” is a joke. Since the seller never replied, after several messages, and Amazon was zero help I decided to open up the battery. As you can see from the pictures the inside of the battery was full of moisture. Also the physical size of the internal batteries is way smaller than the case.

I am all about finding the smallest lightweight batteries for my trolling motor and my 12 volt fridge for camping. This fit the bill perfectly. Charged with both my old motorcycle trickle charger and my new 10 amp solar Mppt controller and solar panel.

I was able to Bluetooth to this battery for one day. I paid an extra $40 just to have Bluetooth. The app is buggy and connection success was about 50% and I’m standing five feet away from it. I uninstalled the app and reinstalled the next day. Now I cannot connect at all. I’ve cleared my Bluetooth cache, no luck. I’ve tried everything. It’s very frustrating.
I tried another phone. No luck. I can connect to any Bluetooth device in the house except for this battery. I’m tech savvy but this thing needs to be sent back.
Edit: I’ve returned the battery and I keep getting harassing emails from seller denying my return claim. I made my claim within 30 days and sent back the item prior to the deadline. Avoid this seller

This product is as good as advertised! I weighed it on my fishing scales and is right at 19.5 pounds! The bluetooth app is easy to download and use! My opinion this is the best 100ah lifepo4 battery on the market for its price!

I never buy batteries, I make my own from raw cells and parts. These have the exact BMS I would use. The cells I would use. The only difference is the box and theirs is better. One star off for 2 reasons. They only use fiber tape at the top and bottom of the cells for compression. The case could provide some compression but there is too much space on 3 of the 4 sides. I know this from videos I have viewed. I’ve never opened mine. If one of them fail, I will open them all and fix the problem. My “FlyPower” battery was much worse and failed after only 2 years of service. That’s why I usually build my own.
Since these have a bluetooth programmable BMS, I recommend setting the per cell overcharge limit to 3.4v or less to insure the battery cells never “gas” or swell. Set the per cell over-discharge limit to 2.9v, You won’t really get any great amount of power between 3.0v and 2.5v anyway and your battery will last longer. The above will slightly reduce the total amp/hours below 100ah, but it might save you from getting a replacement later.
The BMS (Battery Management System) in these batteries (as of this writing) is made by JBD. I recommend them very highly. My “FlyPower” battery most likely failed due to the Daly BMS it used. EVERY Daly BMS I have used has failed.
Lastly, I’m not sure the low temp sensor works on these so make sure your solar and/or battery charger will not charge these below 35 degrees.
