I bought 4 of them, over 3 transactions, on one account. I used the coupon codes that were on their main page. (USAS35, for $35 off $219, and so on)Total with taxes and fees for $921.02. (this number total is charged to credit card). I'm not sure how the -15$ off works through paypal, but I used it with my Citi 2% cash back card. I also had the urlhasbeenblocked-app open which has a 20% payback. That should be another $184 off my total. And another $18 off with my 2% card. At $921 I will have a 48v battery bank at 280ah. That's insane. Hopefully the other discounts work and I will get it all 4 for $720ish. Sorry for the jibberish... Hope this helps someone.

I have 3 of these on a bus to RV conversion that we mostly run in the winter. I was concerned about temps and being able to operate them in cold weather, and so far so good. We went as low as -30 F this winter and when the diesel gelled I was able to use a heat gun run off the batteries to warm the fuel system back up, get additives into the fuel system, and get everything running again.
We had to replace one shortly after receiving it that had a finicky Bluetooth module and didn't like to connect. The replacement was super fast and easy.
I plan to pull our remaining AGM batteries out, they're not worth the weight and space when these work so well.

Edit- I bought mine through their ebay site.

This ECO-WORTHY 12V 280Ah LiFePO4 battery stands out for its very low price, Bluetooth monitoring, and strong value for solar, RV, van, and backup power setups. The battery has been used successfully in cold weather, in parallel banks, and with inverter and UPS style systems, and the app support and fast shipping from Houston add appeal. Main cautions are checkout quirks, extra fees or taxes, and occasional Bluetooth or shipping issues, so the final total and unit condition deserve a close look. A solid budget battery for noncritical power projects.

What's a good inverter to use for a PC to server backup that uses about 500w. These would likely be good batteries for that

Anyone has a tutorial to connect it to ecoflow delta 2?
My delta 2 is connected to one solar panel and powering our garage freezer.
The panel is giving me 480 watts on a good day and by noon, it's already full.

You mean UPS backup for 500 watts? If yes, RENOGY INVERTER is the BEST AND RELIABLE ONE:

There are 2 methods: 1st method is go thru solar charging port with 12V battery like video tutorial below:
https://www.youtube.com/watch?v=Dmhp8_b8GQI

2nd method is go thru battery expandable port with 48V battery like video below:

Anyone else get theirs and have the top of the battery separated from the case?

Mine isn't sealed and I can see the guts so guess it's going back as a return. Also has some minor damage to the outside.

So it's easier to use a battery rack server than just this battery?
This is only 12v and on the video is 51.2v

zero knowledge so need some information are these batteries good for running a John boat of size for 3 or 4 people ? how much running time we got and what lb thrust electric motor good for this setup thanks
Eco-Worthy battery is reliable, built quality, and price affordable. That why, many people are buying. If you read other comment and see how many their already purchased. I got 4 of these batteries myself.

It not depend on the boat size, it depend on your electric motor generate how much watt. For example, if your motor generate 500 watts, it would run your motor 7 hours for 1 battery.

All you need is XT60i to O Ring Terminal Cable [amazon.com] to charge your D2 with the battery but it'd only max out at 200W since your D2 would think you are charging from 8A cigarette lighter via DC. You can also use Ecoflow 500W [amazon.com] or 800W [amazon.com] alternator charger to charge with higher wattage.

You didn't read my comment carefully. Method 1 go thru solar charging port. It's using 12V battery. Method 2 go thru expandable port, it's using 48V battery. So it depend on WHICH PORT that you want to use. Which method you think that easy for you, so you use that type battery.

Probably shipping damaged. Take a pic and contact them for exchange or refund.
