Yeah not much of a concern if it pulls full capacity. However the cell quality can be very different compared to Automotive grade tested cells. It just depends on luck also. And the cells we get are always 1-3yrs old (may not be used but not new stock). So it is a gamble, but for Solar DIY projects with low C rates, it is probably fine.
Real grade A cells from EVE will accompany with factory test reports as given below and will be fully matched. The report has 3 IR values and Tested Capacity.

You can get these Automotive Grade A Cells with test report from EVE directly or SunFunKits.
I was interested if EVE has started marking their Cells that fail the grade A test because now it will be easy for us to identify. According to one of my supplier they have started marking recently, but others have not said anything. Have to just wait and see.
If EVE really does it then it will be very interesting for the market because, suppliers cannot simply tell their cells to be Grade A, like they do all the time now if the QR is intact.
What's to stop them from making up FAKE QR codes like they are doing with CATL cells, in this case they just put the QR code on the lower right instead of next to the vent which they cover up.
The Shenzen Cartels will figure out a way!
