I've heard and seen supporting evidence of two opposing theories on whether or not battery life is conserved at low resistance and in an opposing theory that low resistance correlates to faster battery drainage. From my interpretation of Ohms law V=I*R in conjunction with P=(V^2)/R or P=I*V. Where P is power (watts), I denotes current (A), V for voltage (V), and R resistance (Ohms). I personally believe that with lower resistance correlates to shorter battery life in a regulated mod where power is a constant, along with voltage to some extent being constant. As your left with your amps and your resistance as your variables. So if we look at P=(V^2)/R you can tell as you raise your power output for a constant voltage (Just say 3.7V) your resistance must be at a lower resistance. Then if you raise your resistance the load or power consumption is lower. the power output decreases in value. This correlation can also be made for P=I*V, as your power increases your current rises or your voltage decrease. Looking from only a current load stand point it goes to reason in my opinion that the lower the resistance your going to experience a greater current draw which therefore drains your battery faster. But I have heard reports that a low ohm coil such as the TF-V4 (0.15Ohms) is conserving more battery than a 0.5ohm coil. Can someone explain the correlation between battery life and resistance levels and explain how, if any, voltage plays a role in factoring battery life. I assumed voltage was closely related to remaining volume of battery life while current was the leading cause for battery duration. Correct me if I'm wrong in my assumptions as I do know voltage doesn't remain a true constant in a regulated mods. So if you know the role in which voltage plays in regards to equating variations in battery duration that that would be a bonus piece of information that perhaps I'm neglecting to account for.
