Ok I'm going to go pick up an mvp2 tomorrow (or maybe an istick) but I've got a question, I know the differences coil resistance make on a fixed voltage or even a spinner type battery

but,

once you you have a full control over wattage does it make any difference what ohm coils you use?
i know if I set an mvp2 to 9w then it will run any coil 1.6 1.8 or 2.2 at 9w but is it really that simple?

ps I will be using aspire nautilus mini's with bvc coils

Yes you got it Cowboy192, it's really that simple.

Great thing about variable voltage or wattage is you can set your level to match the resistance of the coil you are using to give you the vape you want.

If you really want to understand what is going on, try a simple online ohms law calculator like this one and plug in the 9 watts with a 1.6 coil. You'll see the battery is providing 3.8V, but increasing the resistance to 2.0 ohms, you'll see the battery increases the voltage to around 4.2v.

All this means your battery does the calculating for you. You might still have to adjust up or down depending on the liquid you are using or the vape you prefer - in fact, I'd recommend it.

Surprisingly, 9 watts on a 1.5 ohm coil vapes differently than 9 watts on a 2.5 ohm coil.

I like lower resistance, even on a VV device - it feels to me to run a little "hotter" - which makes a little sense, as having less resistance does imply it'll heat up a bit faster...

You just have to try both and see if you have a preference.

That's what I was wondering about, I know that an mvp will adjust volts to suit each coil but I wondered if each resistance would have different characteristics? I have 1.6 and 1.8 coils I'll have a play tomorrow

Vw devices will adjust voltage based on resistance to give you the desired wattage the device is set for. So yes, as long as your coil resistance fits within spec you're good to go. However, lower resistance coils will get you a warmer vape because there's less resistance, so your current increases, thus electricity is following faster through the coil, so it gets warm faster.

I dont use the regulated LED jobs but I do have a VV battery and notice that low ohm coils tend to have a greater acceleration even with the volatage dropped, and may have a greater chance of over heating the juice or popping. Anyway this chart seems to be a general way for most people:
