Wow, I think you're right. Nice work!!
Tested a few so far and results are 2470 - 2530 mAh
(discharged from 4.2V to 3.0V on 1.0A draw on B6-mini)

The text on mine is 'N18650 E09E E24D5 50991'
all the cells in the pack have consistent labels except for the 5XXXX at the end.

Yeah 99% sure that last number is a sequential serial number. That's the way most of these Chinese label cells are.
I can confirm 2410-2606. How are these rated at 2200? Very confusing
Can you please post pictures of your cells?

I can.

all above 2200mAh
I've found a green variant.  As far as I can tell they are the same cell, just a different color.  Mine all tested in the 2200mAh ballpark, but with IR in the 80mΩ range, high enough above  the makers reported as-new IR for me to believe these had an as-new capacity similar to what others have reported.  Anyone out there with a high tested capacity on these cells able to provide and IR measurement?
