I am sometimes capable of emptying a 1300 mah Spinner in a day, so we'll see.

Anyway, with the two 18350 batteries in the starter kit, and the two extra 18490s I ordered, I should be able to get through even vape heavy days, and then some.
Does anyone have an opinion about the "fuel efficiency" of the ProVari as compared to other popular mods/batteries?
I already have a VV v3, and I kinda like the VTR more than the MVP from what I've seen on the web, but that one weighs a ton, doesn't it?
