I just order a Nemesis and when doing it I noticed it comes with a ring you use with a kick or the short fuse allowing all sizes of battery to be kicked. I also noticed that Smoktek has an add on for most mods that gives added space for the kick as well as an ego/510 treading for 24.95 including Smoke kick which is 5 - 12 watts or the same as the Kick 1 however the Kick 2 goes to 15 watts. I didn't order the kick at this time as this is also my first mod and wanted to just try one for a while before I decide on a Kick. I also like the fact the Nemesis has a built in air control and takes 18350, 18500/18490, 18650 and all with a kick if needed.
