I've been messing around with e cigs blindly for awhile now but i haven't taken the time yet to really figure out pretty much anything. Most of the time i'll order new atomizers and stuff and just get lucky that they work. Some of them haven't though. I'm trying to start off with this mod Pisa de Italiano 900mah eGo 3.7v - Antique Brass [gv=PisaeGo900-AntiqueBrass] - $18.95 : GotVapes.com, E-cigarette Supplies - Atomizers Cartomizers Mods Juice and more . I'm not sure if it comes with a battery or not and I was wondering if somebody could explain what kind of battery it would need and why. Also any other tips and pointers would be awesome
