I wasn't thinking of anything expensive or fancy, just something to provide electrical isolation from the case, shock absorption, positive placement that doesn't allow the battery to rattle, allows expansion and contraction room without a lot of pressure, and allow no restriction to cooling. Something cheap like this:
Shop Frost King 0.375-in x 17-ft Gray Foam Door Weatherstrip at Lowes.com
Just 2 pieces front and back lengthwise to the battery and maybe 1 on each side. In essence easily suspend the battery in the battery cavity area. Not a big deal, but would probably easily do the job. And did I mention cheap? I like cheap.
$1.39 and it is double sided sticky. The stuff you linked to is only sticky on one side. This stuff is designed to conduct heat weather stipping is just the oposite.

I still agree with Evolv's statement, "40 watts being the most you'll need vaping with TP" but when off TP oh ya 200 watts gimme...
