Here's a simple amp draw calculator for vapers. Leave the efficiency at 90%. Ohms don't matter when figuring amp draw on a regulated variable wattage/voltage device.

But you have to know the true amp rating of your battery in order to use it otherwise it would be worthless. That's where Mooches battery tests come in handy...List of Mooch's Battery Tests
