My VMOD-XL is kicked. I used a stained glass reinforcing copper strip to run from the battery spring to the Kick. I pulled out the bottom of the battery spring halfway, wrapped around the bottom of the spring and pushed the copper wrapped spring back in. Pressure holds the copper strip in very firm contact with the spring. I used some high tack double sided tape to hold the copper strip in place at top beside the Kick. I believe other people have used adhesive backed foil folded over to make it sturdier and soldered it to the bottom of the spring.
Unless you need pocket friendly you might want to get the
Vision Aurora BFT Kit. It's $36 and took a week to get to the midwest. Mad Vapes is Vision's U.S. contact and they will have them in about three weeks. The Aurora works basically on the same principle as the VMOD but I'm finding that my Aurora does a better job of more fully saturating the atty. Todd gave it good review.
