    it is a simple equation

    but do google how it relates to what batteries to use, and limits on resistance and watts to battery specs

    that's pretty conservative, and leaves out amps

    calcs for regulated mods do my head in, i think easiest to put cut off voltage and watts into a calculator to work out amps

    mechs are easy

    yes it's a very vague and incomplete chart, a bit like a taster lol, sorry

    was an rdta one of your atty's in your early days of vaping? thats quite a start.

    well this is what i sometimes refer to check my battery's amps with the resistance of my build

    Ohms Law Calculator

    i said "sometimes" since i already know the limits of my batteries,mod and preferred resistance.
    but when working with new wires or a new battery brand and specs, i still would like it calculated.

    For battery calculations just use nominal volts (Vnom), same as you do for mechs.

    eg: you are running 74 watts on a regulated single battery mod.

    watts = voltsnom x amp, so to find amps being drawn from the battery:

    watts / Vnom =
    74 / 3.7 = 20 amps at nominal voltage, EXACTLY the same as it would be for a mech.

    People do their heads in trying to figure it out, or confuse themselves with the mod output volts and amps, or the coil resistance when that is nothing to do with the battery. ;-)

    Use 4.2 for mechs
