Ok I usually use my Vanilla mod (18350 battery) with my kayfun lite and I like it but I hate that the battery dies too quick. So I just started using my Segelei telescoping mod (18650 battery) with the same kayfun but I start to cough with it and my chest hurts too, what is going on here? its frustrating cause I want to use the 18650 battery.
