What ohm atty do I need if....

[Big Mac]

I'm going to build this? I put this here cause I am a beginner as very much a noob. Please don't say, "standard" cause I have no idea what that means.

cisco 1.5ohm is best i think

1.5 is NOT best with every device. Different devices run at different voltages. An ego type battery runs around 3.3 to 3.4 and you should use attys/cartomizers that are between 1.7 and 2.4. No higher. The Volt X2 runs at 3.6 regulated...they are happier with cartomizers that are at least 2ohm up to 2.8 ohm. Variable voltage can take higher ohm...3ohm and even more. You just have to set your voltage for at least 3.7 and work your way up to the sweet spot.

There is no "best"....it depends on your battery, and on your atomizer and on your juice.

Big Mac...here is a chart that might help you figure things out.

And here is another link with helpful information.

I'd personally use a 1.5 to 2 ohm atty on a 3.7 volt battery, and be more inclined to go with the 1.5 for a warmer hit.

very cool folks, thank you all.

Forthroc, thanks for the chart, not sure how I missed something like that.

Anything below 2 ohms and no higher than 3 ohms. 3.6 volts will give you 7 watts not knowing the voltage drop across the resistor and LED. They didn't list the ohms rating on the resistor. You have to factor that in. THE formula is volts squared divided by desired wattage equals ohms.
Her is a Xl spread sheet that will do the calculations for you.

Here is an updated chart.

Hope this helps.

Oh when you know the ohms rating on that resistor you need to add that to total ohms.

 

[steved5600]

One more thing to think about adding is a Pico fuse. It is small fuse and looks almost like a resistor. At 7 watts and 3.6 volts you want to put use a 4 amp pico fuse. That would blow the fuse if you got to 14 watts.

or just get a variable volt mod then you can smoke any resistance? =)

You probably want either 1.5ohms or 2.0 ohms. My first choice for attys at this point won't work…it's connector is sealed, so it doesn't work on bottom-feeder devices like that.

I'd consider basically any 510 from avidvaper as long as it doesn't have a sealed connector…and try a few from 1.5 to 2 ohms. If that's too hot, go higher.

or you can use a low resistance atomizer

You are right !!
