What batterybrand are you running Vapn? If anyone is running the Ultrafire/trustfire, some (only some of them, most are fine) of those are 36mm long, all one need do is remove one of the preinstalled O-ings in the bottom of the battery chamber. If you are running the AW, one just need twist the cap a bit more, it'll compress the orings down and they soften up with time too.
Btw, i like the in hand photo above![]()
Yes got the instructions and took an oring out for more clearance. Everything is right side up now and fits perfectly. I should have my supply of IMR 16340s soon so I will put it back in. I am actually using some SolarForce batts for the time being. Getting about two or three hours out of em. They are quite old so could be a little weak.
Glad you like the in hand photo!
