voltage drop

I need some help. I recently bought the ijoy capo 100 mod a couple months ago. When I first got it, I was having the same issue I'm having now. The tank would fully screw into the mod no problem but then after a couple weeks, it would stop just about to the end. A gap is barely visible between...

I’ve been vaping for a couple years now and have decided to get into mech mods. I’m doing my research on Ohm’s Law to being but I’m a bit confused by the Voltage Input part. When I’m calculating my amp draw do I use the 4.2V that my battery outputs raw, or do I use the 3.2V that I get after...

Hello all. Just a question about voltage drop, if the voltage of my battery is at 3.8v and the voltage drops it to 3.3v~3.5v so 0.5~0.3 difference, do I need to charge my battery since 3.7v is where I'm supposed to be charging at? Should I just wait until the voltage of my battery hits 3.7v...
