Lid doesn't close when protected 18650 is inserted, would need to be slightly longer. According to the lygte-info article "LiIon 18650 battery comparison" protected batteries are mostly 66.5~69.5 mm by 18.3~18.7 mm at the longest point of each axis.
Lid snaps on easily, and won't come off without a reasonable amount of force, but rocks back and forth while in place, I'd like to tighten that.
