12.8V 300Ah Lithium LiFePO4 Battery With Bluetooth, Smart 200A BMS, 3840W Rechargeable Lithium Iron Phosphate Battery.Max Load 2560Wh .for Solar Energy Storage,Backup Power,RV,Camping

I bought this battery to power my 55 lb trolling motor. I've only tried it out once, but so far the battery works very well. The compact size is a real plus, since my battery storage compartment won't accommodate a Group 31 size battery. Plus, it's light...about 40% of my previous lead acid battery. The battery came 52% charged. I charged it to 100% capacity, which the app showed the battery holding 13.71v. The Bluetooth feature works very well and gives me real-time information on the battery's state of charge. I would highly recommend the battery.

Product it’s great! Charged overnight. However, I accidentally turned off a setting on the app which would allow full voltage to the terminals. Seller was great to work with to educate me in record time and now all us well! Bluetooth connected well and allows you to monitor battery life. Will update further once we go boondocking on battery life.

Excellent quality. Worked perfectly for upgrading my coach batteries in my RV to use with my new solar system.

100A JBD BMS. All 4 cells balance out to within .004v in both batteries I bought and both batteries put out 101Ah. Very small package with huge power. My only gripe is they're advertised with M8 post bolts and they are not M8, they're M6 and really short. Taking one star for the bolt size. Shipping was fast and they came very well packaged.

Very reliable so far. Runs great. Like the blutooth app so I can monitor it.

200AH Mini PUPVWMHB Bluetooth Battery.Arrived earlier than estimated, packed well. Came at 50% state of charge. After removing my existing RV battery box it dropped right into the opening in my truck camper, no cutting. Sweet! It replaced a 81AH lead acid, figure only half of that is usable = 40AH. This 200AH lithium which is fully usable has 3x more capacity at 42# vs 50# for a single 81AH lead acid.Things to know- Not a product issue, but I feel the recommended BMS app seems lacking, but other apps will work. Do a web search for JBD BMS. Also, it's Bluetooth has no switch and is always on which might be a security issue. 3 other batteries I have purchased (a different brand) all have a switch for Bluetooth. I'm concerned someone with a app and bad intentions could walk thru a campground and mess with the battery settings. All in all I'd say it's a nice battery for the price.2 requests for the manufacturer- Add a switch to turn Bluetooth off, and pronounce PUPVWMHB for me!

Long lasting but it does take a while to recharge. I tried 5 amp trickle charge but went to a 10 amp to get the job done. Use it for my Minkota trolling motor and it works great.

Amazing battery for the price. These were the cheapest 100Ah "Mini" size batteries with Bluetooth I could find on Amazon. Arrived completely encased in foam inside a heavy cardboard box, It would be almost impossible for these to get damaged in shipping. Battery is made with a JBD BMS and uses the JBD bluetooth app. App setup was quick and easyily connected to the battery. Batteries arrived with 60% SOC and after charging to 100%, I did a capacity test at 10 amps and pulled 105Ah. There are multiple brands selling this exact battery. I also ordered the "Mehrpow" brand at the same time. Both shipped at the same time from the same warehouse. Both arrived in identical boxes and packing. Both came with identical instruction manual and bluetooth setup booklet. Both batteries were IDENTICAL when taken out of the box because each came with the front name/data label sticker unattached but included with the manual. Literally the only difference between the brands is the sticker they include included in the box. Still, I am 100% satisfied and will likely order a few more.
