At this point it may be a bit redundant, but since I was only able to make this purchase because others shared their experiences, I thought I would add my purchase experience with Jenny at Docan to the thread.
I have purchased two batches of 36 EVE 304ah cells from Docan.
The first was ordered on November 18th and paid with Pay Pal. No payment issues. Jenny told me that these were not in stock in the U.S. and would have to be shipped from China, so I should expect to wait at least a couple months. I emailed on January 19th, and she responded that they were in route to the U.S. Another month had almost past, so I planned to email again on February 19th, however when I arrived home from work on February 17th, a bunch of boxes were in front of my garage door. Happy Day! I'm glad my UPS driver was conscientious enough to bring the boxes up right by the door in front of my pickup, because I had no idea they were coming and they could have been sitting there for a while. So lack of communication on the expected arrival date was the only hiccup in this transaction. No damage. Did the cursory voltage check and weighed each cell to compare with the specification, and everything looked good.
The second was ordered on April 4th. I tried to pay with Pay Pal again, but Alibaba would not let me pay the entire transaction with Pay Pal. I went through several days of song and dance with Alibaba, using different credit cards, calling the credit card customer service to see if they were blocking the transaction, sending photo I.D. to Alibaba, and making some smaller Alibaba purchases with the card I wanted to use. Finally, with no explanation, they accepted the card they had previously declined. This order also had to be shipped from China. This time Jenny had emailed me with the approximate delivery date of June 5th to 10th. They arrived on June 5th, and all was good once again.
Once I heard about the LiFePoQR app, I scanned the codes on all of the battery cells to get the manufacture dates.
The first batch, ordered on Nov 18, 2021, consisted mostly of cells manufactured during the last week of October 2021 or the first week of November 2021. There was an exception with two of the cells that were manufactured on June 27, 2021.
The second batch, ordered on April 4, 2022, consisted of cells manufactured in the first week of March 2022, with the exception of one cell which was manufactured on February 12, 2022.
All things considered, I am pleased with this purchase. No egregiously old cells and no obvious issues.
After they have sat in my basement for a few months, I have finally put together one 4S battery, which I plan to use it with an iCharger X8 to capacity test some of the other cells. I ran one cycle on the battery, and it appears to have capacity in excess of 304ah, but I have some uncertainty over the exact number, so I'll leave those questions for a different post.
