High Voltage/High Resistance vs low Voltage/Low Resistance

[Youssefa]

Bottom line is that you get the exact same heat from 3.5v @1.5 Ohm as you get from 4.9v @3ohms so why use all that voltage?

I think with modern day batteries (VV/VW/Whats next), most would adapt to what ever atomizer you stick on it, reather single or doubled coils in either LR or HR. There should be no figures to plug in and then turn the dial to said setting. By now most all batteries should be Plug-N-Play.

My only confusion is I want to buy some atomizer heads for my Kanger T3 thats on my Ego C Twist 1000mah and I don't know which to choose, either in ohms and in single or double coils. What do you supose a good middle ground is? Are you saying I want notice the differences from all these atomizers like I did when going from a 3.7V regulated battery to a VV Battery?

Lower voltages require more amps. Amperage draw on the battery will kill it quicker.

It's why heavier equipment runs on 240v instead of 110/120.

At least on paper. But things on paper & in real terms can vary.

Higher Resistance and Voltage = lower current for same amount of power than LR. Also at higher resistance a single adjustment of voltage (+/- 0.1v) provides a smaller step change in power so you can better fine tune. On a Twist (3.2v-4.8v) I'd shoot for ~2.4ohm.

On the single coil vs. dual coil, folks have different experiences but I never liked dual coils (YMMV) for taste nor the fact that they 1/2 the resistance (e.g. a 1.5ohm dual coil is actually 2x 3.0ohm coils)

The regulated devices have safety features built-in to limit the output either by cutting off when resistance is too low (the device thinks it's a short) or reducing the the output when the settings will push it past the safety limits. Here's a link to a good review by Phil Busardo that shows measured outputs for varios resistances and output settings: A PBusardo Review - The eVic firmware V1.0 - YouTube (charts start at look at 29:38)

Cool, thanks. Sort of akin to a clipping effect on amplifiers I suppose.
