Hey all, I purchased 4x 280ah cells from Amy at Docan Power, I got 4x EVE LF280K cells from their US Based/Texas warehouse. I emailed Amy directly for most of the experience, docanpower22@gmail.com. She also has a Direct Work Email that is available: amy@docanpower.com.
I did not probe for a ton of questions. I did not ask for any "Guarantees" or anything. I simply stated I wanted 4x cells, with shipping to my address. The only thing I did ask, was that I confirmed they came with 6mm welded studs, so they would match my other cells I already have. She assure they would, and sent me an Invoice through Alibaba to complete the payment. It was very straight forward, and pretty easy I guess. I paid with PayPal, and had it all done pretty quickly. I paid for the order on 7/1/23.
I emailed her direct again, and asked for an estimated delivery date on 7/6/23, because I noticed the Alibaba orders page showed it had not shipped yet. She responded very quickly with both tracking numbers, being shipped via Fed Ex. Tracking showed they would show up on Monday-7/10/23. To my surprise, they showed up on Saturday 7/8/23, 2 days early.
I opened up the boxes, and they were very well packaged, and actually better packaged then I have gotten in the past. No damage, no dented corners etc. Visually they are perfect. Completely flat, nice symmetrical wrapping, the QR code looks to be in tact, without any sanding or anything. I have no proof as I haven't taken off the black plastic though. I have expressed in the past that I am not as interested in the QR code, or if it is A grade or B grade, so long as they pull capacity and are not visibly used. I have them on my desk in the office now, doing capacity tests with the EBC-A40L tester now.
My test method:
1) Fully charge at 40a to 3.65v, cutoff at 2a.
2) Wait for 30 minutes.
3) Discharge at 40a to 2.5v.
4) Charge at 40a to 3.45v, cutoff at 2a.
The first one just completed and it Discharged with 284.9Ah, it also CHARGED with 285.1Ah! Talk about a damn perfect charge efficiency lol.
I will test the other 3 and report back the results.

Capacity Testing:

Cells are very flat and uniform, even with the one with clamps having it at 3.65v, fully charged. Almost no bulging.
