Shortest IMR18350?

I finished my Convoy M2 - MT-G2 build and am using 2x 18350s in it. I have some Efest 800mAh V2 IMR18350 button tops and they are slightly too long, screwing the light together has left a slight dent in the negative face of the cells.

So does anyone know which high quality IMR18350s are the shortest? I will probably go for a flat top and a button top. I will need the button to make the contact between the two cells.

I thought the Efests were some of the shortest, the V2 are button top, might try getting some flat tops and putting a tiny bit of solder blob vs the actual nipple on em

That makes it easy! Thanks very much.

Looks like the AWs are the shortest.
