Right then, I'm gonna be updating the cloud guide later with some updated advice as the stuff on there is rather dated. But, for now, I will type a brief snipppet in here.
Amp Draws, are never what they seem.
Everyone is advised to calculate at 4.2, hell, I calculate at that. But, you will NEVER get 4.2v to your coil on a mech.
why?
Voltage drop.
For example, in order for ME to draw 30 amps, I need to be down at around 0.05-0.06. This is due to the internal resistance of the cell, and the resistance of the mod/rba itself.
As a result, your watts are also way off. I find it nearly impossible to get a true 100watts on a mechanical, even though some of the builds i've used, when put into ohms law using 4.2v , show an indicated 3-400 watts.
The reason we all have to build lower to get bigger clouds, is simple.
as we loose more voltage.
I've seen well executed 0.2 ohm builds kick the ass of 0.04 builds.
why?
As technically, they were getting more power to utilise.
Look at it this way.
You take water, and some tube.
The amount of water stays the same. (Your battery)
As the tube is made thinner, your water comes out the other end at a slower pace.
This, in essence is a really crap example of voltage drop, but it works.
As the tube gets thinner (Your ohms get lower) you get less water (voltage) out.
