KTS Mechanical Mod and Evolo Kick One

[Winchester]

I just bought a KTS 100 mechanical mod and a Evolo Kick One. I just tried to put it together and the KTS is too short with the Kick and a 18560 battery. I there something missing? Do I need to buy an other extension to make it longer? If so can someone point me in the right direction. Thanks in Advance!

You can use an 18350 or a 18500 as is or you can purchase an additional extension to make the mod longer.
