A-grade 304 Eve cells - fake, or real? What to expect?

[Quattrohead]

They look like great cells, possibly better than the 304 so I would negotiate to keep them at the 280 price

Its only $4 savings X 4 , so i would only get a $16 refund, if I kept them. Assuming they are all quality cells , Ive read that the 280Kv3 (with octagon) will perform near 300Ah on average. Is this true? Vs a 304 performing near 315Ah. Is this true? if so its about 15Ah difference and a $16 difference, rough $1/Ah. I honestly dont know what to do. But the extra 15Ah difference would allow me to run a fan (at 2A) for roughly 7 hours longer. Is it worth it , I dont know?

I think the 280K v.3 has a higher cycle count than the 304 too. Might also depend on the shipping turnaround time?

I've just seen the newer Eve 306Ah with a supposed 10,000 cycle count are now available.

I’d still take the cash just to avoid shipping and waiting.

Where?

I think it was a pre purchase on an Australian cell site.

I just got shipping label to return the 280Kv3 , I think I will proceed inorder to get the 304. Hopefully I get some good quality 304

bottom line if you don't' get a manufacturer report... its probably grade B.

How can I verify a test report?

This is my first purchase and I went with Amy Wan (Shenzhen Luyuan Technology Co., Ltd.)

This is the test report link she sent me

Links to her own website domain and no manufacturer heading on the document. Am I safe or I should be worried?

Thanks
