anyone know where to reference the sizes of the batteries to the generic battery size. i.e. CR2, CR123, AAA, AA, etc. i am trying to find a 3.6v that is the size of 2xCR2's.
yeah, i bought another coleman max led flashlight and i have another heatsink for it. wanted to run lava drive, and need 1 cell to provide 3.6v it currently uses 2x CR2 and i wanted it to be rechargeable b/c i already have a trustfire multi-charger
i already have 1 coleman max led with an 18650 in it. had to put it on a lathe and shave the walls.
that's it in the background. when i enlarged the diameter of the battery cavity, the groves in the side were opened. a screw up on my end, but it turned out pretty neat to me.
