Roughstack Max V2 is a simple yet beautiful tube mod made in the United States. Each unit is individually machined out of aircraft grade aluminum. Version 2 has easier to screw threads compared to the first version. Due to this, they are not compatible with each other. It runs on either one 18650 (3.7V) battery, two CR123A (6V) batteries or two 18350 (7.4V) batteries and uses 510 atomizers.

i bought this mod from madvapes i fixed the threads on it butt when i use a 306 on it with an 18650 the draw is really stiff unless u clean the connection and blow it out some of my cartomizers quit working on it on 6 volts butt i think it might be the batteries i thinking about getting some high drain ones
Cons: Paint, switch and the price of a replacement switch are all horrible. Switch placement makes it a pain to use a tank unless you get at least an inch of clearance.
My paint job was marred during production and yet was allowed to pass inspection.
Pros: Vapes like a beast and I like the fact that you can replace the batteries. You can replace the batteries with whatever brand you like and can choose from 3 different models. Switch placement makes it difficult to accidentally activate.
