Well like the title says... I'm new to the ECF, well at least posting, been lurking for some time now.. I aslo just got my first mod, a Maxi Roughstack V2 from madvapes.com. To start off i kept it simple, 3.7v 3000mah 18650 UltraFire, 2.5ohm 306 atty. After a few hours with it i really like it, it hits great.. but i do have to be honest.. i just placed an order for a pair of 3.7 1200mah 18350's for 7.4v (stacked), and some 4.5ohm 510 attys. I've never vaped on anything over 3.7 so i wanted to give it a try. I do have a question, Should i pickup a "high voltage" juice? Thanks for any info you may be willing to offer.
