Hi guys, have a little confusion about the Ohm's law on a regulated device. Now say my nominal voltage of the battery is 3.7v, and I want to vape at say 45W with a 0.5ohm coil.
1. The voltage which is displayed on my screen is the battery voltage or the voltage required to push out 45W or power?
2. Should I always ensure that the voltage displayed on the screen is lesser than 3.7v?
