This is a 20650 cell, NOT a 26650. It is 20mm in diameter and 65mm long. It is another of the larger-than-18650 size cells available along with 26650’s, 20700’s and 21700’s
This cell performs as well, or a little better than, the Ampking/EBAT/Efest/iJoy cell but not quite as well as the elusive Sanyo NCR20700A.
The shorter length of this Sanyo 20650 offers mod builders and companies a different option without compromising performance versus the mid-performance 20700’s. I do not know of any companies that have a mod that fits this size cell but a sleeve should allow them to work in a 26650 mod.
There is also the LG HG6 30A 3000mAh cell but I do not know when I’ll be testing it.
I am rating this Sanyo cell at 30A and 2900mAh.
The two cells that were tested were purchased for that purpose by me.
