Yesterday I got a new information from my supplier. I was supposed to order EVE LF230 (230Ah) cells from them. But it seems there has been a change on how EVE is sending out rejected cells (Tested to be lower than Automotive Grade) for auction to the Chinese market (grey). According to the new information EVE has started marking the letter "B" on the QR code of LF230 and LF280K cells that were being auctioned. I have attached the pictures below.

It looks like they have also scratched off the serial number part. However the production date code is still intact, which is good for us. CATL has been scratching off the entire QR codes on their Grade B cells, but I think this is a new step from EVE.

If anyone has got this new info, please share. We need confirmation if this is going to be the standard going forward.

If EVE is really taking this step, then we will see huge changes in the market, as all of the cells that we get are these rejected cells that are being auctioned off at a much lower price. But all of the sellers claim these cells to be Grade A and are selling at a huge profit margin. However most of these unused cells will pass our capacity test and is still suitable for Solar ESS, so we really cannot complain. We will have to see how they handle this new marking of the reject cells. Note that there are a few legitimate Grade A suppliers like SunFunKits or buying directly from EVE Energy Co. As far as I know, all the other suppliers send us these non-automotive Grade B cells.
 
Is there a guide to translate that numbers and letters on the QR Code label on the EVE cells into something understandable?

Yes. You can Decode as follows:

Date Code is as follows:
Character#1: 9, A, B, C: 2019, 2020, 2021, 2022
Character#2: 1-9: Jan-Sep; A-C: Oct-Dec
Character#3: 1-9: Day 1-9; A-V: Day 10-31

This is a standard format and works on most cells from EVE, Ganfeng, CALB, CATL etc.

Easy way is to just use this online Decoder:

This is the guide from EVE for the end user to know what is the battery level they get.

Well stated. Any updates (factual).
 
Looks like I have a chance to buy some real B cells... At 150 shipped per cell for 230s I'm likely going to stick with prior distributor, just wish they had US stock.
