and now, totally incorrect
current is not voltage
I see, so amps and voltage are different things.
So how do you calculate what amps you are pulling from the batteries with a mod like that? assuming the batteries are rated at 2C I can calculate what their maximum current would be.
If I was using only one battery, taking 4.3 volts from it with a 2.5 ohm tank I would only be pulling 1.7 amps from it (according to the online ohms law calculator I am using), so a protected 18650 would be fine, but I am unsure how to work it out for a 2 battery box mod of this type, or is it the same deal?
