Low Voltage and Low Ohms or High voltage and High Ohms?

[jnn26]

After I think I've got this whole thing figured out, at the end of the day I still can't decide if a LR carto is producing more vapor than a SR carto at higher volts. I almost decide that the SR with higher voltages is doing it but then I wonder if it's just my imagination. I have an Ego-C 650 Twist with Smoktech 1.7s, Boge 3.0s and been runnin a 1.8 ohm Ego Vision (ahem..) Clearomizer. They all seem to work fine my fav being the Ego Vision.. but wondering if A higher Ohm with Higher volts one would hit better.. or if its really the same. Just needing some suggestions and advice from a few of you vapin vets out there. Thanks!

Higher will draw more power. I use ego twists and a provari. I vape on Boge LR 2s. Set them at 4-4.3v and enjoy. Try it there.

It's all about watts. Doesn't matter how you get there.
Ex. (3.5v X 3.5v = 12.25 /1.7 ohms = 7.21 watts) [at 2.1 amps]
OR (4.6v X 4.6v = 21.16 / 2.9 ohm's = 7.29 watts) [at 1.6 amps]

Same vape but the second one uses less power. More efficient.

Feldwin just curious about your example. Why does 3.5v X 3.5v = 12.25? Are you saying series batteries increases voltage? Which is wrong but still would inly be 7v in parellel. Please understand im not trying to correct you im just curious.

No. That's just the formula for power (watts)
Voltage X voltage / resistance = power.

Also, the last statement should read same vape but the second uses less current (not power). More efficient.

You will always get more consistency by using regulated variable power, preferably a variable wattage model PV. I would rather use a higher voltage than depend on LR's that degrade quickly to produce warmer vapor. 4.5 - 5.0 volts with a 2.8 ohm standard atty/carto or even better a 1.5 ohm dual coil atty or carto. (and regulated power, of course)

Yeah i figured it out almost as soon as i posted it. Sorry.

Another take on it... 3.0ohm cartos allow for a 0.3watt adjustment (e.g. @4.9v = 8.0watts, @5.0v = 8.3watts) so for every 0.1v adjustment it's easier to fine tune the vape (e.g. 2.0ohm - @4.0v = 8.0watts, 4.1v = 8.4watts). So for me it comes down to more control over flavor/TH with the ability to make more granular power adjustments.
