To figure out which way current is flowing through the mod we need to examine what batteries are. All batteries contain one or more cells which is a working chemical unit inside a battery. Each cell has three main parts: a positive electrode, a negative electrode, and a liquid or solid separating them called the electrolyte. When a battery is connected to an electric circuit, a chemical reaction takes place in the electrolyte causing ions (atoms with a positive electrical charge) to flow through it one way, with electrons (particles with a negative charge) flowing through the circuit in the other direction. This movement of electric charge makes an electric current flow through the cell and through the circuit it is connected to. In our case that would mean that negative electrons are flowing through the mod body while positive atoms are flowing from the battery and through the atomizer coil. So there is something flowing from the battery both ways at the same time, negative electrons in one direction and positive atoms in the other direction.
I am not an electrical engineer, nor do I claim to be even close to being one but I worked in a battery making factory for 3.5 years and have a general understanding of how they work. I also write many of my posts in Cebuano/Bisayan, use google translate and then try to correct the translation as best I can. This may or may not cause some confusion at times, especially when I use it to translate other people's posts.
