Haha, I already bought 4 of these.
By far the cheaper Lifepo4 ever. Less than .10 per wh.
Rated at 1920wh and I've tested 2 of them and got 1950wh.
Was going to post this but it seems I always get deleted everytime I post a deal.

These are not cranking batteries, they are designed to supply current at a somewhat steady rate. You would not want to use these type of batteries as your starting battery.

Description says 120A max continuous discharge x nominal 51.2v for your x4 series, so I come up with 6144w max output.

Working back from you numbers, it appears you might have been multiplying 12vx150ahx4 batteries to get that number and were referring to capacity?

In that case, multiply the 150ah x nominal 12.8v x 4 batteries for 7680w/h. Then multiply by inverter efficiency (check inverter, but 80% is conservative in most cases) to get usable capacity, which in this example would be 6144w/h

Not really the right tool for the job. You're better off buying a purpose built UPS that has battery, inverter and charger built in - something like an APS brand.

These LifePo4 batteries are usually used for solar/home energy storage, RV house batteries, etc.
Gotcha, thanks!

If I series 4 of these, I will get 7200 watts output capable correct?
Technically yes, but you would be supplying 48V, not 12V. This is not usually advisable unless you connect them using a separate BMS and/or know how to monitor voltage and current of each series connected unit. It's a lot like if the cells within the battery were connected without a BMS, and that would not be safe enough to sell as a consumer device.
If you put them in parallel, the voltage will stay at 12V, but the current would add. You could potentially pull close to 500A which would require very large cables, between batteries and to the load. if you know you're not going to pull that high current, then use breaker(s) and/or fuses to be sure.
If you do this, charge/discharge them all to the same voltage before connecting, otherwise current will flow from the higher voltage to the lower voltage through a wire with presumably very low resistance, which means max current, likely more than the BMS's can handle before triggering their own protections.

Good for campers/rvs but you'll want one that is selfheating if you do any cold weather camping.

I don't know, this just seems like one of those "too good to be true" situations. Reading through their other listings on eBay they have a bunch of almost identical batteries with wildly different prices. The cycle life is 3000, 4000, 6000 or even 15,000 cycles with other specs being similar.

Has anybody found any videos where these batteries have been tested and disassembled?

Search other threads here on Eco-Worthy. There are older Youtube teardowns (DCguy) that show poor assembly, but more recent teardowns show much cleaner, coherent assembly, uses JBD BMS (this one with BT incl), and capacity testing so far checks out, per other vids and your fellow SD'rs. My DCHouse battery (same as Eco-Worthy) shipped from SoCal (Chatsworth?), so even a return wouldn't cost and arm and a leg back to China.

Unfortunately some good deals were lost due to ratings minimums designed to cut back on spam, but now they are moved to the new Marketplace Forum. There are still some cases where the brand itself is banned, but generally all submitted deals are posted Smilie

Dang how do they sell these batteries for so low compared to the other popular brands? Gotta be B cells instead of A cells.
Ecoflow is $189. I'd buy that over this any day. 5 year warranty, reputable company.

I'm buying it to replace the UPS battery. This is much bigger and has a much longer life than what a UPS has.

So would if it has similar capacity at $189, but I am not seeing it. Do you have a link?

UPS's are usually tuned for lead-acid specs. This may work, but may not charge completely

Look up some reviews on youtube and you can find $10 off codes. Or google for codes.
