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

How did you test its capacity? What is the start and stop voltage?
I use this kit from Amazon.
Pretty much what most YT use to measure battery capacity.
The only Eco Worthy battery, 24v 100ah, that didn't test to it's capacity.
It was short by about 40wh, not significant for me to complain.

Ecoflow is $189. I'd buy that over this any day. 5 year warranty, reputable company.
Good Lord man.
Eco flow is a 100ah battery.
This is a 150ah battery.
50% more capacity.

Just got this message from the seller, seems sort of bait/switchy:

Hi ,
Sorry to bother you. Firstly thank you for purchasing our 150ah plastic cased bluetooth batteries,
but we are sorry that due to the current stock shortage they are not available to ship at the moment,
but another metal cased 150ah battery is in stock.
Maybe you are ok with us sending the metal cased 150ah batteries?
They are about the same size as the plastic model batteries and have the same bluetooth function.
Looking forward to hearing from you.

Best wishes, Oliver
Damn, lucky you.
Take those metal casing for the same price.

Damn, I answered a few questions on the first page and now it's 9 pages long.
I honestly don't think anyone that has more Eco Worthy stuff than myself.
They're not the best quality you're gonna find but their pricing are hard to beat.
The picture below are all 12v 100ah batteries in a 24v system.
I have 4 of their 48v 50ah metal casing and now I just bought 6 of these 12v 150ah to update an older system.
I actually bought 2 of them earlier when hey were $213 after 20% off but at $168, I bought 4 more.
I bought tons of their solar panels too.
I think the tariffs are coming so I'm predicting we won't see these pricing after while.

Is there a single device that converts a big battery like this into a "solar generator "? I think I am asking for a single device that will (1) charge this battery via 120V AC (2) inverter output 120V AC pure sin (3) charge this from solar panels (4) output USBC and 12V DC. It seems like there would be a fair amount of demand for this. Thanks!
Yes. If you look for solar inverter, it will do what you said. Eco worthy also has a 5000w inverter with discount as well. But I don't see much review about it. If you trust their batteries, then trust the inverter too. Otherwise, I read Victron has good inverter (pricier tho).

Just make sure your DC converter can charge lithium batteries. My 2021 travel trailer was shipped with a converter that is supposed to not charge lithium. It will cost me $300 to replace my converter in the stupid WFCO all in one power distribution thing that was installed in my travel trailer.I think I'll just stay with my deep cycle lead acid battery. Lead acid has the advantage that it can be charged at below freezing temperatures, but that's the only advantage I can think of.
Some DC converters on newer model RVs have a jumper that allows them to support charging lithium batteries. Have you confirmed that yours does not have this functionality?

I bought it and got the same message about the plastic one being out of stock. I see no metal 12V 150Ah one with Bluetooth on their site. Kind of concerning as I want to know what I'm going to receive.

Could I use this for my kid's powerwheel? I am sick and tired of those batteries almost never lasting a year...
Won't fit and your kid will outgrow that powerwheel by next year anyway. Give the little guy a hug instead.

Yeah, I'm guessing they're trying to offload some old/refurb stock of their discontinued metal case batteries.

None of it makes sense. The Bluetooth 12V 150A battery is listed as new and in stock on their site. Metal one is out of stock and doesn't have Bluetooth. They sent me an image of the metal one and it's looks like the label was photoshopped on with Bluetooth and Low Temperature protection.

Exactly.. this is the type of scam I'd expect to see on AliExpress, not eBay.

Would this be good for a battery backed up sump pump? Seems We go through one 12v car type battery every year or two.

Thanks! They are a little bigger and pricier than I was hoping. I was thinking of making more of a DIY jackery. The "Solar Inverters" seem to be more for permanent install solar systems. I will keep looking though. Thanks again @dong888

EF Alternator charger has been listed here at SD multiple times at $189/199. I doubt anyone is buying it at $600. But even at $189/199 it's still not cheap but it's a solid piece of kit and has multiple uses. Whether it's worth it depends on your use case. But having bi-directional charging, controllable charge rate, and all of the functions controllable thru the EF app makes it worth it to me. I can use it to draw power off my EV during outages as well as use it to add capacity to my power stations. You can find lots of info and arguments about it on previous SD threads.
Interesting. I saw that deal and thought from the comments it was a hack that got fixed/shut down... but it seems it's still possible to get (I didn't actually order but it showed up in cart). $189 for that cool 800W charger is a lot more tempting than $600! I haven't looked into how it would pair with external batteries like this one, but for my use case (keeping a refrig running at ~110W), the 180W recharge rate I can get with my $12 cable is probably sufficient. (I thought about getting a 24V battery or running 2 in series to get 360W... but this deal seemed too good to pass up.)
