LOL, Will replied to me.
"Because they should all pull the same exact figures, and it should be 103-110Ah. That is the issue"
I really didn't know that there is an unwritten rule that a 100ah rack battery should return 103-110ah capacity.
Again, I'm not disputing if the cells are grade A or B or how long it will last.
The main issue is capacity and he's nitpicking the shit out of it for no reason.

Will should have included his search into why the one unit didn't perform as 'expected'. That would have been FAR more useful for viewers than the appearance of Will's 'blessing'.

The more you comment, the more it's obvious that you're new to this field, don't know what you're talking about, and clearly have ZERO idea who Will is, and his expertise.
Batteries should always have more capacity than their actual rating, other manufacturers do this, so yes, it absolutely should be marked down for not competing with the industry.
If you watched the video, at the end he did actually state that it was still worth the money, even accounting for less capacity than the others. However, I don't think he was actually critical enough on how bad they were with the BMS temperature sensors and how they were "attached".

What BMS are used in these batteries?

Until a user inspects, we can only speculate. They use JBD BMS's in other batteries, so have a partnership there.

Is this UL listed? You know what would happen if your house have fire because of any electrical issues and you have none UL listed component connected to your system…

Noob questions, I have 7kWh solar setup and I'm wondering if this battery is going to be perfect for my setup. And, is it scalable if I ever need to add more and how since it's not rack mounted.

Depending on your inverter and whether it has the programming for this particular battery. Some inverters are a proprietary system where their board many not see this battery and you won't see the charging/battery level with the inverter. So you have to check that first with your inverter. If your inverter/charge controller is compatible, you can easily add more and daisy chain it off each other as you scale it up. You just put it up side by side to each. Will Prowse is a youtuber that tests different batteries/charge controllers/solar panels and you can get an idea of how a very similar battery like this one is installed and mounted. 6:20 mark of the video. battery.https://www.youtube.com/watch?v=8W4dTw_hXdU

Not a comment on the quality of this product, but it seems kind of crazy to me that a battery that holds $2 worth of electricity costs $2500.

Eh, I'm sliiightly inclined to agree with him based on what you said. Grade a cells will pretty much as a rule exceed the rated capacity. The fact it didn't exceed it may be an indicator of what kind of cells they use? Or maybe it's just a one off coincidence? In any case we have a sample size of 4 from him and 25% isn't great odds?

Great price though for what you get. A good $700 less than eg4.

Sample size of 4 = widely variable and unreliable results, so you can't read anything into the 25% under-spec rate. Not saying Eco-worthy is building good or bad batteries, just saying you can't make any assumptions here.

Example: I've bought a single battery from Eco worthy, it exceeds capacity. So: Failure rate of 0%. Should I trust this? Good companies do QA testing in mass scale: hundreds, thousands, or more units.

Just felt like dropping some basic statistics here…. 😁

EW have sought UL listing for their server rack batteries, suggesting it will arrive in spring. No word yet on this particular unit. I simply can't buy these larger units for home backup until they have UL listing.

His test was wrong.
This review shows 107Ah:

Downvotes are surely because you said Will's test is wrong. YMMV, even as Will displayed in his vid. However, the vid you posted is the vid Will *should* have made for this unit.

I am assuming that you have solar system without batteries and you want to add the battery to you solar system. What you are asking is called grid-tied system and it is not simply hooking up a battery to the system. In most cases, you will need a permit when dealing with a grid-tied system since incorrect setup can backfeed to electrical company and injure workers when they work.

That is why you see huge price difference between the battery together with solar system vs this type of system. Most people who bought this battery use it as off-grid system. You can, however, connect off-grid system to your home via a transfer switch (this is what people with generator do). Look it up if that is what interests you.

I live in Texas where couple of companies offer free electricity at night. Is that possible to buy this and store free electric energy at night and use it during the day time?

And that's cheap for energy storage. 14.3Kwh of, say, rechargeable AA batteries would cost closer to $6k.

Yes, this strategy works. Free sun by day (solar panels), free grid by night, living large.

So if I typically use 32kWh/day then I would need 3 or 4 of these to power my home for a single day? Is that how it works?

I lived in Texas for a while. "Free" energy at night still charges the transmission rates, so it's more like 60-70% off at night. You might also have a minimum that you get billed for every month.

But the bigger problem is that this battery holds about $2 worth of electricity. If you charge it and discharge it over and over again, it'll start holding less and less. You'll probably end up spending more on the battery than you'd save on electricity.
