Does anyone know what voltage/wattage I should be using with these 3.2 ohm vision carts that they have had good experiences with? I'm using 70/30 pg/vg. And it seems like I get the best hit if I hold it upside down. I only filled this 2nd one about 5/8 or more and gave it a couple upside downs to get the wicks wet.
If you tell me the Voltage and Ohms of something you are using right now I can tell you what should work with a 3.2 ohm Vision.
The Math is like this...
Watts = Votage Squared divided by ohms
Say you find you like a 2.8 ohm carto with your juice at 4.3 volts.
4.3 volts squared divided by 2.8 ohms = 6.6 watts.
So for your juice you like it vaped at 6.6 watts. To find what voltage is needed for a 3.2 ohm Vision you use this formula
Voltage is equal to the Square Root of 6.6 watts times 3.2 ohms
(6.6 * 3.3)^1/2 = 4.6 volts
Once you know what wattage your juice works at it easy to get the same results for Any ohm carto or atty. Just take the Square Root of the Watts times the ohms and Bingo, you get the Voltage.
BTW - A Provari makes doing all this a Snap.
