Tank Drains Fast?

[MartinLuther]

So I recently purchased a kangertech genitank mini and the ohms on the coils are 1.5. The battery is an EVOD 650mAh 4.2V battery so it's decent. Anyhow, my tank drains really fast same with my battery. any help?

Well, how many ML are you going though in a day and how many battery charges are required to vape that? Also, what other setup are you comparing to?

As far as I know the EVOD puts out a constant 3.7V. The lower you take the resistance the more power you're going to generate as per Ohm's law and the more juice you'll use per puff. 1.5 ohms is pretty low
