QR Tag Conflicts - EVE & CATL

New member, first post. I recently ordered and just received from a reputable vendor what were described as EVE280K Grade A cells (4). They arrived with what I see referred to as the new terminals. That kind of surprised me, but no sweat with my plans. The cells look new to this first-time prismatic cell buyer. The boxes were marked EVE280K; no spec sheets included. Shipped within about a week.

The QR tags look legitimate. Text starts "04QCB76", as expected. However, QR scans consistently come back as CATL cells and "001CB31..." I've used a couple different QR code scanners with the same results. The entire, QR-decoded string shows with gobelpower as CATL 280Ah cells. If I understand correctly, "04Q" is EVE and "001" is CATL. I haven't seen this double-holed, large terminal style mentioned with CATL cells.

Confused! Counterfeit? I'd mention the vendor, but have an unrelated issue that I want to see how they resolve first.
 
Can you take a picture of the cells and QR code? Maybe others can tell if it looks legit or not.
 
Wow knock off EVE terminals :ROFLMAO:

Just who exactly is the "reputable seller" I'm seeing this phrase come up more and more.
 
@Elwood64 Who did you buy the cells from?
They look different than the claimed grade A cells listed below. Your terminals don't have the marker nor are the polarity symbols white.

The terminals also look too shiny. From pictures I've seen, the real EVE terminals are brushed matte aluminum color.
Possibly a knock off...

But I would do a capacity test on them. If they give the rated capacity, does it matter if they are EVE or CATL ?
 
Ohhhh wow, this thread is seriously hitting the "conspiracy theorists" who make wild assumptions and make conclusions from them.

RE QR Code Verification, Post Photo's of it showing everything, useless with part of it blanked out... Serial #'s are NOT a security risk ! Geez Louise!

FYI, EVE has several factories and there is a bit of variance on the markings due to different generations of machinery & labeling systems. Whether the terminals are shiny or satin is also irrelevant. Be aware that those "terminals" are not unique to EVE either.

Hrm,

I think people are just starting to wise up and are catching the scams early, if the sellers don't dot there i's and cross there t's they are gonna get it.

And that is how it should be!
 
No conspiracy theory. They're from EEL via Amazon. Shipped within a week from Ontario, CA. As mentioned, there's was an unrelated issue with the shipment that I'll share when I hear back. I think it will be of general interest, but don't want to throw them under the bus without an opportunity to respond directly to my concern first.

I'm new to the forum, so am trying to get a feel for what's appropriate and what isn't. The QR code comes back as valid for CATL and text shows to be EVE. I have next to zero experience judging the legitimacy of these stickers, but nothing otherwise obvious jumps out at me. I wouldn't have thought much about them until being surprised by the terminals.

@meetyg Would you assume they're either with conflicting stickers? I expect truth in advertising.

Why does the serial number matter? The manufacturer code from the text and that from the QR don't match.

I wouldn't expect then to advertise one thing and provide another.
But your case is fishy with QR code showing CATL...

Can you tell me if the QR code looks etched into the aluminum or powder printed?
I had a strange case with supposedly 105Ah EVE cells (bought via Aliexpres):
I bought 1 batch of 4 cells, and the etched QR code displayed these were EVE LF90K cells. I complained to the seller. Capacity testing proved that they were in fact 90Ah. As part of the dispute, instead of getting a refund, I opted to get a discount on 4 more cells (for my 8s build).
The new batch had the QR codes printed on the cells (with some kind of powder print), in place of the original QR code.
Now these codes show 105Ah EVE cells, but not all information could be found.
So I think the seller/distributor probably had similar complaints and decides to fake/copy some 105Ah cells codes (probably changing the last few digits).

Can you tell the difference between top cell (fake code) and bottom cell (legit code) ?

I suspect that maybe the same thing happened to you.
Not sure by the pictures, but just might be.
 
I'd say powder coated. None of the four have much texture and all have that kind of uniform gray background. They do have kind of a holographic look where they're clear from one angle and the camera can pick them up, but practically disappear from a slightly different angle. That could just be from the reflective background. They look real close to the "Reprinted" photos shown on the GobelPower QR page here.

I just noticed that, using the scanner recommended by GP and "Custom Search" settings, all of the QR codes come back with the identical string. Manufacture date of 12 APR 2022. Just eyeballing them, the QR blocks look identical, too.

Does CATL include a serial number in the QR code? I see that EVE does. All of the "EVE text" on the labels show unique serial numbers, otherwise identical up through the date of manufacture (12 JUN 2022, if I follow an earlier forum post).
 
Thanks for letting us know, I would demand money back and use the QR code as proof or a significant refund.

Why all these companies can't just advertise the cells as grade B like currentconnected & 18650batterystore, Gobel (kind of but in the end they state it has a B) and official Luyuan Store.

The argument is NOT is grade B good enough, the argument is that are we going to keep letting these Chinese Sellers do there little scams and have no consequences, so far it seems to be yes, as long as the price is low enough we don't care what you do.

CATL is The Biggest LFP maker in the world and pretty darn good stuff generally and if they were advertising EVE 280 Cells and substituted CATL 280AH cells cause EVE is having a hard time filling demand, then it's not a bad thing. Just something to be aware of if/when building more battery packs. CATL cells are usually more costly than EVE's as well, especially if they are properly Matched & Batched at the factory.

Some companies mark B grade cells which do not pass the tests for any number of reasons but not all. EVE for one started doing that earlier this year to cut down on teh sheisters causing them all sorts of issues. I hope that soon most companies will do so but do not expect it from smaller companies while for hue companies that CATL that will involve more work on their part simply due to their size.
 
I've gathered that CATL cells are at least as good as EVE. With the labels showing both, logic suggests they're neither.
 
Post a link to the amazon listing, as long as EEL doesn't advertise them as grade A you are probably OK.

Grade A = Cell with manufacturer test report.

Actually there really isn't even Grade A, its Really Cells that pass QC and Cells that fail. But I doubt any seller is going to say, "Reject Cells for sale!"

ALL CATL cells being sold online are Reject cells, they call them grade B.

EVE on the other hand does sell EV/Grade cells that pass to the public these come with manufacturer test report/cell.

So if you are comparing grade B EVE to grade B CATL then you will be ok. However, if you are comparing grade A/EV/Cells that pass QC with manufacturer test report to grade B CATL, then no you got taken advantage off.

So it will all depend on what the seller said on there listing.
 
EEL is then full of :poop:

But no one on this forum is going to care, so if you are paying them $800 for reject grade than you must have money to burn. Far Cheaper to buy from 18650batterystore or sunfunkits or luyuan all have real grade A with manufacturer test reports.

Docan is a far better deal if you what you want grade B catl, people are reporting over 295 AH on the CATL 280s. Yes the have a fake QR code on the side but speaking on wh/$ you can't beat. Although 1 thing for Docan is that the CATL 280 may actually be 302, we don't know becuase the original QR code was removed.
 
It's quite a jungle for noobs to navigate. Fraud is another matter. I get what you're saying, though.

Thanks for the leads.
 
These are my own Grade A bought from a reputable company (famous last words)
You can use it to check if you find any differences from yours.
If you need better pics, let me know

You're at least one-up on me. The manufacturer matches between QR code and label text.
