Docan 280 EVE cells - 2023 Quality check (update: Bad experience - scam beware)

upnorthandpersonal said:
This could very well be a fake QR code. The decoder at https://www.gobelpower.com/lifepo4_decoder.html also says the code length is wrong.
It could be that Docan has decided to remove the 'B' mark from the cell coming form EVE and replace the entire QR code - which I told them at some point not to do because it will cost them customers. Is this a sticker over the original one? Or erased and redone? Are the other QR codes the same number or is there a variation?
Alternatively, it could be that EVE changed code style and this is not recognized by the scanner yet, but I somehow doubt that..

i agree , these seem to be fake QR codes...
you can verify this, but you would have to take off the black sheet, if re lasered there will be a distict difference between new lasered metal and original
 
Unfortunately I am waiting for my JK BMS to arrive. It will take max 7 days for it to get here. I will inform you guys
 
Spoke with docan and they told me to check them via this website:

Docan told me the app took the barcode wrong. It seems it didn’t see the number ”1” in there. So they might be ok.

I don’t know how is this possible as I scanned 2 cells in a row. What do you guys think?
 
If you use their website or app to decode the QR code, Docan or Gobel Power controls the information that you see. Any 3rd party app should be able to decode your QR code.

No it is scannable now by the app also ONLY if a put the barcode manually.

The barcode however, the more I see it the more I think is reprinted or on top of the old one. Should I peel-off the black sticker?
 
I didn't have much luck with APP scanner either on my EVE cells, looked mine up manually.

Here’s another QR. No, there’s not much variation between the 2 random picked cells. I don’t know whether it is a sticker or not. I”ll have to pull the whole black tape and I don’t wanna do that as I may have to speak with docan about it.

Peel of the black covering see if you see sanding marks around the area where the QR code is, if you do then the took grade B cells with the B mark and re-lasered them.


See this guy: https://diysolarforum.com/threads/n...ese-eve-lf304-cells-new-ok.60171/#post-742713
 
These guys know what theory are doing. They sand it and put a lot of glue so you need to clean it to see it. Ughh
