What measurement drains a battery

Hey everyone. Recently went from a tfg4 to a tfv8 (using the dual cool rba). So from four coils to two. I'm using an rx200s with three lg hg2's. I noticed now the current reading on the device has dropped over 5 amps, but firing at the same wattage due to build type. Will I experience a higher battery life now? What exactly causes the batteries to drain faster?

milliamps x time = maH

amps x time =aH

units of time are hours.

.5 hours is 30 minutes, eg.

So, do the math. Your batteries in series are roughly 2 aH

2/ load in amps = hrs mod will run.

You can see the fraction gets smaller as load increases, which means less runtme.

Same wattage, same drain. Yes there will be some variance due to circuit inefficiencies. Coil current (amps) is not necessarily equal to battery current. Generally speaking, if you fire a regulated mod within ITS limits for a given wattage the resistance of the coil makes no difference in battery drain.
