So I bought this used Apollo mech mod. I just got done cleaning it with a soft bristle toothbrush getting all the connections and threats just useing some soap and water. I then poped on my rda with a 6 wrap 26 gauge single coil, and my efest 1600mah battery and I was hardly getting any vape and the battery was literally burning my finger after like 3 seconds. Plus I'm the bottom of my efest battery there is a burn mark where the pin from my magnetic button hits the battery. I also notice that the button kinda moves abit and when I'm pressing it, depending on where my finger is and how hard I push is how much Vape I get. I have to push really hard to get some Vape production but then the button burns my finger. What do I do??
