I got the smoktech magneto a few weeks ago and i am using a 3.7 V efest battery at around 8 to 10 amps with the nautilus tank. For the past week i noticed that the vapor production had diminished significantly. I started checking all my connections and i noticed the floating pin on the magneto seemed to me melted. My mod never got too hot so im not sure why this happened. Has anyone else run into this issue?
