So I have a Wismec Presa mod and while I liked the size and the battery life was ok, th atty threading has stripped after only 5 months. I'm in the market for a new vv/vw mod and I'm debating between 18650 and 26650. I run a .6 ohm Nichrome coil at about 24w and would like better battery life than my Samsung 25r gives me. However, I don't want to carry a brick as in the size of the mod. I've been looking at the SXK Zero mini and the Encom TNT80. Any help would be appreciated.
