In wattage mode, it is going to auto adjust the voltage to achieve the wattage selected. So while firing the wattage will always be what you set the mod to, but the voltage will jump around all over the place to get that wattage.
I'm using a tfv12 prince max mesh coil (0,17 ohm), I'm pushing 110Watts on it.
so, 4.2v / 0.17 = 24.7A 24.7 * 4.2 = 103 W
So the result is alright, but when it comes to fireing the mod itself displays a fireing voltage at 2Volts only.

Here's a video of the problem to clarify.
I use some 2.8 amp hour batteries, with a max discharge rate of 10Amps, I know this is not recommended but it works for shorter periods.
Your 110 watts is requesting roughly 19 amps per cell. You are using 10 amp cells, they are not able to deliver the proper current thus your device is scaling back power.
Keep in mind the batteries voltage sag. Voltage sag is a drop in voltage due to the current draw and the batteries internal DC resistance. Lower CDR batteries generally have a higher DC resistance, thus a higher voltage sag. Higher current draw also results in a higher voltage sag.
Not only is performance suffering, but you are running a higher risk by over drawing your batteries. Not recommended!
Regulated mods don't follow ohms law. So that equation is irrelevant.
That voltage jump is normal. It is doing exactly as I described in my previous post.
The batteries you are using are way too low for what you are trying to ask them to do. They would be OK to use at under 20w in a dual battery mod. You are abusing the crap out of those batteries and it is not only not recommended, but could end up hurting you. I would recommend to stop using those batteries immediately.
I have a feeling the 10A is the pulse rating, and they are under 3A CDR.
They actually do, just applied differently. The equation is correct but missing the voltage calculation.
V = √PxR. So technically, the applied voltage should be 4.32 volts based on the requested 110 watts for a 0.17 ohm coil. And from there we can calculate the current draw at the coil. I = V/R or 25 amps. But these are not the most accurate devices, deficiencies will almost always yield a lower or higher applied voltage.
These might be a decent choice for you. On sale until the 17th, and Use code timmerz10 for 5% more off.

The batteries are definitely a huge problem. Smok is the other problem.
