    Okay, I've been using an Efest 18650 v1 2000mah 10amps in a fully mechanical mod with a 0.5 ohm coil..
    I calculated this in an Ohms Law calculator as follows.

    Voltage = 4.2v
    Current = 8.4
    Resistance = 0.5
    Power = 35.28

    Question, will my efest handle it with ease? or am I in the risky side of vaping? Don't want to blow my face off..

    Thanks ECF!

    In all honesty, if you are worried about blowing your face off, stay above 1Ohm :)

    i like to use no more than 50% of the rated power of my battery for no other reason than it's easy to calculate, and it allows a lot of margin for error, because batteries deteriorate as they age and go thru a number of charge cycles. In other words, i treat manufacturer data with suspicion.

    I like 30A batteries for sub-Oh coils to allow that margin.

    I'll just raise the resistance of the atty in about 0.7-0.8.. Thanks guys!
