I've been putting off the VV thing.. I wanted to give my ego batt's a chance with different carto's, I tried fluxomizer's, 306's, tanks and the like. " I'VE GOT TO HAVE MORE POWER". I think I'm goin' for a provari. My questions are, does it have a 510 connection so I can use all this stuff I've collected? Is there a downside to this device? What is the difference with the batteries (18490 and 18650) How many batteries should I get?
Any thoughts would be appreciated. I figured this would be a good place to post this
