Vision Spinner Voltage Settings

[unslaved]

My Kanger Evod I got today comes with a 1.8 ohm head, considering that what would be the best setting to set my Vision Spinner to voltage wise so I get the most use out of the head before it burns out. One last question ive got 2 2.5 ohm replacement head, whats the best voltage setting for that ohm rating as well. Thanks.

Basically it fires from 3.3- 4.8 volts. Turn it down and slowly dial the voltage up until you hit your sweet spot...sweet spot will be diff for diff juices. Here's a chart that may help "generally":

With the 1.8 ohms head about 3.7 volts BUT it may not be for you. Try lower and go up slowly.
