Pretty sure protected 18350's won't fit. In any case, protected Li-ion's don't work well in single battery VV mods because the batteries protection circuit kicks in before the batteries useful charge is depleted due to the draw of the boost circuit. Same reason Provape recommends IMR batteries because the Provari gets wonky at higher voltages unless it has a high drain battery in it. I'm also quite sure this is why Joye limits the Evic to 11w so it can use longer life Li ion 18650's.
I only get several hours out of a 18350. Yes, I vape way to much lol. Personally, I rather carry a plastic battery box with 2 couple of spares in my pocket rather than haul a big honking 18650 tube around. Battery box has simply taken up residence where my Zippo used to reside.
I hear ya, I only get about 4-6 hours of heavy vaping with 18350 imr 800mah batteries, and I am starting to think that I need more batteries. I think I am about to order Efest Protected Li-ion 18350 900 mah batteries real soon. Oh BTW does anyone know if the flat tops will work in the innokin SVD and natural too?
