Noob question here but, how on my ipv mini 2 "70"W it says the max output of the device is roughly 8.5V but the input voltage only up to 4.5V and all batteries I have found run a nominal Voltage of 3.7V. It's a single battery regulated mod I'm just curious if there is some feature that basically cuts the voltage in half to make it safe to "crank up" the wattage. I just wanna ask before I do. Oh and I'm running an authentic mxjo 2500mah 30A 3.7V 18650. My builds currently are looming in the .25 to .65ohm range.
