4 PCS Bluetooth 12V 314Ah LiFePO4 Lithium Battery MINI, Max. 4190Wh Energy, EV A+ Cells, Built-in 100A BMS, 15000 Deep Cycles Battery with Low-Temp Protection for RVs, Solar System, Off-Grid

Battery is working as hoped for/expected!We bought this battery along with a 1000 watt pure sine wave inverter to use as a power pack for our cargo trailer toy hauler/camper conversion...mainly to use with our 48 quart Wolfbox 12/120 volt car refrigerator and it ran the refrigerator for approx. 24 hours non-stop via the 12 volt plug connection.Note 1...I used a power plug-in 120 volt meter to check the wattage pull on the battery with the refrigerator on it's "Max" setting and it was pulling between 48-54 watts.Note 2...the battery and inverter ran the lights (two 40/42" led light bars) with no drop/hesitation.Note 3...we tried to run our microwave (1400-1450 watts) and it started up but the power dropped down and you could tell...this was probably because the inverter was set to normal and not the heavy load setting??? I plan to try it on the heavy load setting later on.I hope that it will continue to give us this type performance for our camper/toy hauler in the future and for an acceptable amount of time.Hope the information above was helpful!

Good battery. Use it to power my tool through a 2000 watt inverter. I bought 4 of them so I'm never short of power in any emergency.

I had bought 2 batteries previously from e—-bay and really like them . So I ordered a 3rd one so I can disperse camp with my little camper . I have a 12 volt refrigerator and wanted to make sure I could stay for a couple of days. I have been highly satisfied with with them

The Bluetooth app doesn't work with my phone, android 15. The word mini is deceiving, battery doesn't fit standard battery box on trailer. Two batteries wouldn't fit between frame so requested return. They sent labels and sent back for refund, we'll see. If they would have fit in the frame I would have kept them.

Tremendous power. Purchased two for my motorhome. Powers everything from A/C to microwave for about 3 days without having to run generator.CUSTOMER SERVICE IS FANTASTIC. WOULD BUY AGAIN.

Just installed and time will tell if they are good or not. It seems like a good product. I will do a review later.

Work greats, better than the conventional lead acid battery and way cheaper than AGMs for a better product

Installed in my 21” Nitro with 300hp Mercury. Took it out for the first time since installing this dual purpose lithium and so far it’s performed flawlessly. 1200 cca starts this 300hp beast with ease and run all my electronics for 2 days without charging (except when engine is running) and again performed very well. Bluetooth is easy to use you just have to be within 15-20’ from the battery for it work which is no issue while on the boat or around it. Don’t waist $100’s of extra dollars on the well known brands, this lithium battery will do everything you need for a cranking and electronics. What you waiting on, get one.
