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

Quote from Tropical_Farmer :
I originally bought these for outside location for pool pump, but couldn't resist that might get better deal with metal case and same specs so now I will use for inside battery bank as I suspect in Miami, FL the metal cases would not do good in outdoor moist environment. "Thank you for your understanding. We will send it to you as soon as possible when the stock arrives at our warehouse. Best wishes," I sent them back a message asking to confirm they are grade A cells and not returns even though they have assured me, "same performance as the plastic model battery" so if they are inferior I will dispute with ebay. Metal case should be easier to pop open and check out insides.
By the time you find out if they are inferior, it will be well past the dispute timeframe. Lower grade cells always look good at first.

I'm surprised that people are taking this seller at their word, when the seller is already misrepresenting the in-stock status of the product. In my mind, a seller who misrepresents the in-stock status, is likely to misrepresent anything else about the products they're selling.

It is one of those "it's too good to be true" deals, but I'm not worried with eBay's protection policies. Everything is documented within eBay's messaging. Also, with forums like this, their reputation could be tarnished very quickly. There is probably a reason why, and it may not be so nefarious.

Right on the first page, I posted that I got 2 of these already and I tested them out at 1950ah when it's rated for 1920ah.
It's not "too good to be true"
Do research people. It's super easy with the internet these days.
Plenty of people on YT that taken these apart and vouched for them.
I have no clue on why they are selling for $167 same as their 100ah.
I bought the first 2 at $213 and bought 4 more since they were so cheap.

As for as the metal shell version.
These were made before the plastic version.
They cost more but I don't think they have BT built in.
If they are offering them as replacement it's not bait and switch as they cost more.
I also got the same message for my last 2 batteries and I even said I can take the metal as replacement but they didn't offer it to me.
If BT isn't important to you, the metal casing is definitely better.

You're mixing up two different things. It sounds like you received the plastic version, which has been torn down and tested. That's what I paid for too, but the seller told me it's not available, and hasn't answered my question about when the plastic version would be available. So, I'm being offered the metal version, which has some "mystery BMS", "mystery cells".
If the seller was being "above board" they would remove the listing for the out of stock plastic batteries, and add a listing for the metal ones with proper specs.

I ended up letting them send me the metal one. They claim it has low temp protection and Bluetooth too. If it doesn't, then I'll complain and have them send me the plastic one. I also intend to open it and take a look at the inside.

The 150A JBD BMS is these would be pretty easy to swap in/out, even at the shipping warehouse, and the newest BMS are almost all including BT now. The case situation is simply a stock issue...as these are a slightly larger case to fit in slightly larger 150A cells, they simply ran out of plastic, and are still shipping completed units in metal cases. I will be thrilled with a 150A battery w/ metal case, and BT would be icing on top. They haven't had the 150A version, in either case, for very long...and the 100A version is slowly being upgraded to the BT version of BMS during these 20% off sales.

There are some pretty crazy differences in the claimed cycles. The linked version on eBay has a picture that says "Up to 15000 cycles" (same as the webpage) while the same picture in the listing description says "1500+ cycle" instead. The label on the pictured battery says "more than 4000 cycles" which looks the same as the webpage. The only metal case version that I see "with similar specs" (but without Bluetooth) on the webpage says "Up to 3000 cycles". The picture sent by the seller conveniently doesn't have a cycle count listed, like the 100Ah model on the webpage.

I have 2 that's still haven't been sent.
I would happily take the metal version.
Usually when company use metal casing for their batteries, it's better quality than plastic.
I'm not saying it is but I would take my chance with the metal casing as Eco Worthy charge more for the metal casing version.

How is metal shell better. Where did you find listing thst they cost more. All of these costed more in the past. Do you have a web page cache showing the detials of it. When everyone is moving to plastic why would they be moving to metal.

Plastic is much cheaper.
Metal case keeps batteries from swelling.
Search all the expensive 48v rack batteries used for high end stuff.
They all use metal casing. ​
