I don't know what I'm doing in this regard. I have a detonator box mod vv that I use at 4V and like the (yes outdated) DCT carto tanks but don't know what ohm my cartos should be. Also what does mah higher or lower do for one? Could someone direct me to some sort of chart that shows the optimal pairings? I have some 1100 mah eGo twists coming and want to try higher voltage but don't know what kind of tank to buy. One of them is coming with a vivi but I don't much like clearomizers and can't accept any leaks as I am afraid of poisoning my dogs.
