Thank you, this is a great find, essentially ~$105/kWh (280 * 12.8 = 3,584 watts).
For anyone interested, these measure just under 18" long, 9.4" wide, and 8.7" tall, essentially less deep than 4D or 8D form-factors, closest to a 4D about 3/4" wider.
Group 4D: 20.75 x 8.75 x 9.8 in
Group 8D: 20.75 x 11 x 9.8 in

Do these things have a history of catching on fire?
They 'have a history of losing [their] shirt.'
My concerns with these batteries:
1) Lack of UL certification
2) Warranty support, affordable but expensive to ship back for replacement... I think you pay both ways
3) Chinese manufacture with Chinese chipsets... do you connect to it using their app and Bluetooth or not?
Main reason why I have not jumped on these. To be fair, even "US" or other country made batteries may have the same chipsets, but the app... you need to trust the app developers.

These are Lithium IRON Phosphate batteries, not Lithium Ion.
The latter are often in smaller devices and have been reported to catch fire on occasion and in certain situations. Given that there are literally at least 2 billion phones out there, the number of incidents is minor, but an issue, in particular if this is your device.
Having said that, Lithium IRON Phosphate batteries are not likely to catch fire.

To what he is asking, I have looked at this brand for the past year and manufacturing defects that allow for units to catch fire are not top of mind. Usually the defect is a bad cell or BMS fails (can no longer charge or balance the cells) or other component (bluetooth, temperature sensor) and it may need to be shipped back for repair. The warranty does not cover all shipping costs, so it can be very expensive to ship such a heavy and hazardous item.
Hold up. He appears to be inquiring if this manufacturing has issues with their batteries catching fire. All batteries have a risk of thermal run away when treated poorly or if the BMS does not shut them down... say when it is 120 degrees outside and the batteries begin to overheat and swell or swell from overcharging.
My understanding is that a big, BIG reason why these are 'safer' is because when they combust they do not create oxygen as a by product. The creation of oxygen is what allows lithium batteries to burn even after 'smothering' or a fire extinguisher is used. Others can correct me, but LiFePO4 batteries can be extinguished much easier. However, just like a wood fire, the area around it may stay hot enough to reignite, so that is a concern. Using this understanding, many people are stuck on the thought that these are just plain safer than Lithium batteries. The answer is YES they are safer because you can extinguish them easier, but they can still catch fire if not configured properly or if mishandled.
I learned about this while researching if I can place such batteries in my basement. The 'experts' go back and forth. What it comes back to is that insurance companies say NO, and if you do then it should be in a separate area with fire suppression and in a container which can slow the spread of any fire. Waiting for the day that insurance companies use the energy credit records to confirm that you have batteries installed and drop coverage or deny claims. They should, technically, be stored away from the house in a climate controlled shed... but not many have the money to do that.
DId the rules change? I bought all my stuff around 2020 and was under the impression that none of it qualified because I didn't get code compliant stuff and it wasn't professionally installed, but maybe I'm mixing state and federal programs.
I would love to get credit now for what I didn't get before.

Eco-Worthy is pretty damn good quality IMO. I have a few panels and some of the server rack batteries. Very impressive for the price. Not even sure how they are making any money TBH.
