Nice. Thanks for testing.

Do we know who is the original manufacturer of the cell?

4

Panasonic is the OEM for this cell.

5

why would we use this cell when there is a 21700 that has 5100mah? speaking about the acebeam 21700

6

Well, this one can do 30A, and is slightly smaller.

Something like the Samsung 40T, or even 30T if you want 40A, would be better in the 21700 size bracket.

Anything, what do not you hear (for do not say: “B*llsh*t)!! It is Yongde Lixin, the manufacturer of this cell (confirmed by Dennis, technician at Vapcell), here is the official web page of this cell: http://www.ydlxny.com/index.php/work1/show/26. html

P.S: Do not pay attention to the picture on the official page, it corresponds to a pre-production version of the cell, contact the positive pole has been changed since the transition to mass production.
