Unregulated parallel box mod. 2v like a regular mechanical mod or another mod running only a single battery. 17 ohm zipper coil on it. Please do not try this on your box. I modified the 1590B Hammond box (I cut out the back and sanded all the side to eliminate th Best unregulated/mosfet parallel box is the Titan by SilverSteam, not always easy to get but it's fantastic. If you put one cell in the wrong way, there's nothing to short out, right? Whereas if you do the same on a parallel box, it's I am in the process of building my first dual 18650 parallel box mod and after A LOT of research I will give you a list of what I believe are the best components for building a box mod. It has a Yes, I know there is a MOSFET in it. I have looked at many different schematics and I plan on running a mosfet. This way, the use of a non-rated switch will no longer be an issue.
