I want to find out which batteries I should upgrade too. I'm building coils for kayfun and plan on getting dripping atomizer. I read that places sell fake one so I want legit.
Is this a question? Do you want to know where to buy quality batteries and be certain they are as described? Look to RTD Vapor or Lighthound for genuine AW IMR and Efest IMR batteries.
Also what kind of chargers should I have is the one that comes with K101 not good?
See vendors above for quality brands. As there is a lower incidence of charger forgeries, you can look to Amazon or eBay for best pricing. The Nitecore Intellichargers are good quality/value.
Also what the best affordable dripping automizer?
Any of the Youde brand RDAs are good quality/value, in the $12 to $40 range. EhPro, Tobeco and Hcigar are other "known good quality" brands. Stick to vendors that tell you the brand. If all they state is the "model" or "style"... it could be pure crap.
