We have these batteries here at work ...
When you get yours:
Make sure Bluetooth app connects.
Make sure resting voltage is roughly 13.1–13.4V charged.
AND the easiest way to see if its real or fake -- The official Eco-Worthy specs for this battery says about 61.7 lb ... if it shows up at 35–40 lb, something is wrong.
A 280Ah was right at $2450 ,,,,
And that was with a very crappy BMS - if at all ...
so yes ... a 280Ah with excellent BMS for $222 is a pretty damn good deal ...
Community Reviews
This ECO-WORTHY 12V 280Ah LiFePO4 battery stands out as a very low-cost way to get a large smart battery with Bluetooth monitoring. The app can show charge state and estimated runtime, and real-world use includes camper, boat, fridge, and backup power setups. Pricing context makes the $222 tag look unusually strong versus typical $350 plus pricing. Main cautions are the heavy weight, lithium charging requirements, and reports that checkout pricing, codes, and availability can change quickly.
The battery app can display charge state and estimate remaining runtime based on usage.
The battery can support 12V loads like a fridge and can extend runtime with solar and MPPT setups.
The battery can be used to charge an EcoFlow Delta through its solar port.
The battery can be charged to about 14.2-14.6V to help balance cells and maximize battery life.
The price can jump from the cart amount to a much higher total during address entry.
Checkout can fail with a security error message that prevents processing the request.
Warranty information may be hard to find, and the terms or policies link can redirect to an Alibaba page.
The battery is not suitable for engine starting and it has different charging requirements than lead-acid batteries.

Does it mean I can use a ring terminal to xt60 cable to connect this thing to my ecoflow and use it as a "2nd fuel tank" while still taking advantage of the output ports on my ecoflow (DC cigarette plug, usb-c, and 110v AC)?
At this price it's almost too good to be true so I want to double check. Thanks!

In total I spent about $2k on the 48v system I put together (with an ROI of about two years) - bought bulk 2awg wire, crimper and lugs to save on pre-made battery cables. Bought 3kw of used solar panels from solar installers off Facebook Marketplace for $130. I didn't go cheap on the critical parts that could cause safety issues though. If you're still interested in putting something like this together, let me know if you need part recommendations.
I do no suggest getting a 12v 5kw inverter. Aliexpress lists some high output 12v inverters, but they are super sketchy. Most reputable inverter manufacturers don't go past 4kw for 12v. Even then it isn't recommended because you will need to use 4/0 gauge cable to handle almost 400 amps of current. You would still need to get two of these batteries because each battery only has a 200a BMS.
recommendation for a more or less inexpensive charge controller for this battery to use with the panels?

Here is the link:

In my main browser, logged in, I see the price of this (ECO-WORTHY 3584Wh 12V 280Ah, from the ECOWORTHY-US official store) as $321.
In the same browser, but in a new private window, i see the same $321.
However, turn on a VPN (neighboring US state) and open a private window in a different browser, I see the price as $256. NOT "welcome deal, max 1 per shopper", but the same "SuperDeals, max 3 per shopper" advertised to me above.
I wasn't aware aliexpress did this. Amazon tried it (DVDs, circa 2000), and abandon it due to consumer backlash. I can't find any real info on this.
