So I have a wismec presa tc100 watts . I have a Vapecell 26650 4200mah battery in it. I have started vaping on 50 to 60 watts on dual fused clapton coils 0.25 ohms. When I am vaping the mod says that it runs at 13/14 ampers and 3.5 volts. Today was my first day with this coil setup and I was surprized (in a bad way) when I realized that it nearly died from like not even one hour of vaping ( one hour for a whole day ). I'm using a simple wall charger. I tried to write all the details that I can think of for you guys/girls to have a lot of info. So is this normal because before when I was using it on another coil setup a whole day of vaping draind only like half of the battery.
