I last traveled in October so I don't know how SOP may have changed since then. I was told to just put all my vape gear, and separate bag of juices (which has to follow the rules for liquids) into 1 Ziploc bag and then to put that into it's own bin, like your shoes and what not when you go through security. Batteries I put in cases, tape closed, and place with my charger in my checked bag.
Remember to not fill the bottle all the way in the reo, the pressurization causes it to autofeed, I just travel with them empty and clean, then slap a bottle in when I get outside.
