I recently got a Provari v2 and am curious about a few things. Whenever I check the battery, it auto fires for 16 seconds ...? Just wondering if anyone else's device does THAT. My next question is less important and a little more personal. I personally favor rebuildables, and can't seem to build one that will fire at 6 volts. Is there a wattage limit as well as the amp limit? Because my kfun is a little upset. Provari seems to not want to be over 3 amps not the 3.5 advertised on the website. I've done a bit of research on my own and haven't returned any real results, come to trust the people here on e cig forum (new member, but I've lurked long enough to know some folks names).
