Up to 10A (Rated maximum current) the discharge curves look good, the overload at 15A is not as nice.

Temperature stays reasonable at 10A

Looks like the cell under the wrapper has changed, for the worse:

https://www.e-cigarette-forum.com/t...a-1100mah-18350-without-a-wrap-change.887429/

...I purchased four of these Vapcell's, verified their authenticity, and did a quick check. They perform a lot worse than the last time I tested them. I do not know this cell's ratings and I will not be retesting it......The new cell can be identified by its smaller raised portion at the bottom (versus the older cell I tested). The newer cell also has two small weld points on top (under the top insulating ring) and a slightly larger gap between the top crimped portion and the body of the metal can....

Darn shame, these work very well in my JetBeam RRT01.
Purely anecdotal, but I was told by a local vaping distributor that sales of the 18350 are declining to the point that finding factories willing to produce them is becoming more difficult.

The Vapcell website indicates a new version of the 18350 cell was released on 1-15-19. Not sure if this is the same cell referenced in the post above from 11-20, or if it's an entirely new cell. The cell now has a continuous discharge rate of 9A instead of 10A.
