Why do i have to crank the voltage up after cotton re-wick??

[daralike]

So I have some 1.8 ohm coils for my ProTank2, when I use them stock my sweet spot is between 3.4-3.8 volts on my ego twist. The weird thing is when I take out the silica and re-wick with cotton I have to crank the voltage up to 4.4-4.8 volts (maxed out) to find the sweet spot. Why is this??

This sounds like its probably due to either
A. you may have the cotton packed a little tight and its taking a little more heat to draw the liquid to the wick
or
B. cotton and silica are two completely different materials that react totally different to the same amount of power.

1.8ohm coils are too low, at least go to 2.2ohm. I prefer the 2.8ohm, so I can crank it up without tasting a burnt flavor. I usually buy the 2.5 ohm just because there's only one place that stocks the 2.8ohm at a good price.

Are you checking the coil resistance after you pull out the silica and replace it with cotton? A lot of things could happen to a coil in the process of doing that.

I would say 1.8 is too high... go down to like... 0.5-0.8

1.8 ohms are fine. That's what I wrap mine to. The only thing I can think of is you are flooding the coil? Did you replace the flavor wick?

 

[IMFire3605]

Wick is to thick and/or tight in the coil, should only have enough cotton in there when threading to where the friction wants to pull the coil the way you are pulling.
Another reason could be when you threaded the coil, you grounded out inside the cup, make sure the coil wires are equal distance from the walls of the cup, and the coil is centered over the air hole in the bottom
Another reason, you have to much wick resting on top of the coil if you installed a floating flavor wick to stop flooding.

Twist won't fire that low. They cant sub ohm

1.8 ohm's is great, as long as I can crank the volts up to 8.5 volts that is, better at 12 volts, but hey, that's me
