What are you guys using these for?
Power my window Midea 8000 AC unit in the summer and a portable heater in the winter (right now), connecting to a 12V inverter, of course.

PSA: Your credit card may fail when paying they want to make sure it is not fraud - you will have to email them a copy of ID, Statement, Credit Card. Paying with Paypal, the transaction will go as a cash advance and start incurring interest as soon as it posts. Reddit r/AliExpress.
Best way pay via PayPal with any card and get 6% cash back which brings down to $205

Can this be used as an expansion battery for my Anker C1000 using the solar input?

I don't know about the c1000, but if it has a 12v solar input jack, then this should work. I plan on doing the same with my eco flow.

Eco-worthy is a reputable brand. They've had an AliExpress store from the beginning, although most buy from them via Amazon or Ebay.

Not expansion battery, as the power station can't charge this battery, but for the other way, you can just buy XT60 male pigtail, and a DC breaker and wire them all up to the battery.

It says its a certified original, so not new? Does it have used cycles? Is there a way to check this?

The Bluetooth on mine immediately disappeared (connected once, showed stats, then since the next time my phone was in range it has refused to connect). But this is such a good price I might just keep using it without Bluetooth lol.

Some have suggested discharging it fully resets the BMS and re-enables the bt function. Let us know!

I just bought 2 at the same time, along with the 12V 20A Smart Charger and was able to use coupon code USBF95 for $95 off $519 order. This brought the total to $212 per battery, plus tax. Of course you need some sort of other item for filler since the two batteries alone were $517.

I had been thinking of getting another Ecoflow battery since the Delta 3 Plus I have doesn't last long enough running the fridge during extended power outages. Then I saw this deal and after some reading realized you can safely connect these batteries up to any solar power station to charge the station. Two batteries is great, since that allows me to take one to be recharged. And $428 for over 6kWh compared to the $1000+ I was considering for 3kWh is obviously amazing. Since I just need to keep a fridge running, it doesn't matter that these basically trickle charge the Ecoflow, though I guess you can connect them in series to get a higher charge rate.

For new AliExpress people, suggest you first add a credit card (Chase Freedom Unlimited worked for me, after I cleared a fraud alert and Ali re-ran the payment) to your account profile before checking out. This cleared an issue I had with it not wanting to take the coupon for "security reasons".

Also cash back site is up to 15% today. Sounds like these are also fine to claim for the 30% federal tax credit?

Ships from USA, legit brand with decent components for a solid price. Even with all tbe hoop jumping BS, can't beat 1120AH of capacity for anywhere from 820 to 960 bucks depending on the gods you were praying to at the time. 62lbs a piece, pretty much 4 bucks a lb for lifepo4.

Welll, managed to get 3, and will pull off the 4th over the weekend.

Used the PayPal pay in 4 20% cash back to pick up 2 kits of the eco worthy 130w flexible panels so that'll be 8 panels, 32lbs…awesome weight savings for 1k watts at $277 net after tax putting that at 26 cents a watt. Now gotta put together the rest of the system.

Break even frontier is somewhere in the 600 days of usage, so even at great deals solar for RV use will take a lotta days to make financial sense. Luckily hobby decisions aren't financially driven.

Thanks for the suggestion. I tried discharging it connected to an Ecoflow Delta 3 Plus via the Ecoflow alternator charger, but that didn't seem to reset the BMS. But maybe the alternator charger didn't let the Ecoworthy battery discharge fully? I have turned the start voltage all the way down and turned off the "starter battery protection" function on the alternator charger that is supposed to prevent discharging your car battery completely, but alas.
