So this question has been bothering me for some time now. what is the correct way to measure amp draw from a battery through a mechanical mod?
a. fully charged battery, 4.2v, fires a 1 ohm coil, drawing 4.2 amps from the battery
b. fully charged battery, 4.2v, fires a 1 ohm coil, except .2v are lost in the circuit (voltage drop), sending 4v to the coil, drawing 4 amps from the battery
which one is right and why? i have been assuming A. because better safe then sorry, and would not plan on pushing batteries further to the limit if B. was true, but i just like to know answers to questions like this
