Hey, I need some advice... I have a KBOX 200 and a Joytech CuBox. My CuBox inspired me to make a small version of the KBOX 200 which I disassembled and already have the chip but was wondering if a single cell 18650/22650 would work to decrease size. I don't have any intentions of going up past 150 watts and was wondering if a 3.7 v cell would work fine as long as the cell has a discharge of 40A, correct? Would it even function correctly if I don't have a certain range of amperage? I don't know where to start and if my idea is even feasible... Any advice...?... Thanks in advance. I've been vaping for a few years now on and off and decided to take it a step further from cloud chasing as you can see XD.
