As noted above, don't count on a Provari upgrade to VW anytime soon. The standard and mini have exactly the same electronics, only differ in the size of
batteries they use (and therefore they themselves differ in length). The standard and mini each have their own milled designs on the body to distinguish one from the other.
Provape makes and sells
battery extension caps and also sells off market
extender sleeves (and bases) in order to jump up a battery size from the default size for each model.
Tatroe Mods makes the sleeves (rings) and base for Provape, and the parts can be ordered separately
here. I've used these to allow the Mini Provari to use 18350, 18490, and 18650 batteries.
