7.7 volts on a 0.59 ohm coil is 13 amps.
Even if it was the stated .45 ohms it would be 17 amps.
RDA coil, somethings wrong

I don't vape at 100w I just tried different wattage, usuall vape @ 50 to 60w
Yup. And your calc is using a fully charged battery. With a battery at 3.3V the battery amp draw at 90% board efficiency goes up to 34A. Of course, the mod is going to shut things off fairly quickly, specially if the battery is not up to that kind of amp draw, but it's still pushing things a bit.
60 Watts is what Many People consider to be about the Top End of a Single 20A CDR Battery.
But back to your RDA...
With a Single Coil in it, is the Opposite side Air Flow How blocked off as Letitia mentioned?
And have you tried just a Single Wire Build? Not as Fancy Looking. But Lower Mass. And Quicker Ramp-Ups/Ramp-Downs.

Things get a bit squirly in a regulated mod @UncleJunkle. The mod output is 7.7V, the battery voltage depends on its state of charge minus voltage sag due to internal resistance.
Here's an easy way to figure things out: Battery drain | Steam Engine | free vaping calculators . Set that page up for a regulated, VW mod and play around with the resistance and wattage looking at what happens to the battery drain and you'll see what I mean
Yeah... I actually did the Calculation for 3.9 Volts. But your Mention of the Max Battery Amp Draw is at the Lowest Voltage a Regulated Mod will fire is Right on the Money.
Because it Directly Opposite (Watts Law vs Ohms Law) than for a Mech Mod.
Most Regulated Mods cut out at around 3.5 or so Volts. 3.5 Volts @ 100 Watts is a 31.75 Battery Amp Draw. And that Exceeds All(?) of the 18650 that I know of.
I'd give them a Shot.
Single Wire Coils (SWC) don't look as Cool. But they also give you Better Battery Life because they Don't need such Ungodly Wattages to drive them.
Single Wire is also Dirt Cheap to Buy. And SWC's are Dead Simple to Make.
Ya, the way we safely set things up in mech mods makes things confusing sometimes for regulated mods!
Most of the time with my regulated mods I'll swap batteries before the mod shuts me down. But those times when I miss and run them down all the way I think they are generally around 3.3'ish V. And that means the mod is probably shutting them down around 3V due to voltage sag if it measures voltage while firing. So 3-3.3V generally. At least in my experience
Yeah... at 3.3v if the Mod will fire at 100 Watts, that is Definitely in a Danger Zone Battery Amp wise.
That is another Reason I like Single Wire Coils. I can get a Massive Hit from 35 or 40 Watts on a Single 26ga 0.42 Ohm SS Single Coil. No Need for Super High Wattages.
And my normal 25 Watts is fine for sitting around Shooting the Snit on an e-Cigarette forum.

If I were you, before I would change the coil(s) I would try anything I could think of with what I had in there now. One thing that has already been suggested is to wick tightly and that is IMO a good idea. It's easy to do and once you've explored this you'll see if it makes any difference.
Also, make sure you have the coil high enough so it's not sitting in any juice underneath it, and make sure you don't have any cotton touching it under the coil. Start at say 30 watts and work up as you go to see how this setup vapes through the wattage range. Everything you learn doing this will help you going forward.
Thanks, I see now but I don't actually understand (but that's OK because I only vape at 20W or less 
). I'm looking at what the coil sees and not battery drain, which can be significantly different.

I vaped at 30-40 watts for quite a while. Right now I've got three squonkers going here. Running one at 10 W (dual coil), one at 8 W (single coil) and a mech at around 15 watts, all using 30 gauge wire. A few years ago I was regularly vaping 30-40 watts and thought wire thinner than 26 gauge was a real pain to work with, LOL. Whatever works

I run 26ga SS on my Regulated Squonkers because that what I found worked Best on Mech Squonker. And that's what I started Squonking with, a Mech.
For my RTA's, I run 28ga SS/1.1 Ohms at around 12.5 ~ 16.5 Watts. 30ga is just a Tad to Thin for my Fat Fingers and Tired Eyes. But I used a Lot of it when I first got into Rebuilding.
Funny how our Vaping Habits can change over time.
double coil like this it's kinda massive....
Go with a simple round wire double coil 26ga or a little thicker wire I guess u may have already like 6wraps each coil....
Ideally I would get a thin Clapton coil like I always do with double coils like 28*2/38 fused Clapton or 30*3/38 fused Clapton or anything similar and use 5wraps per coil cause u can use this at lower watts and have fast ramp up time with good flavour and clouds bruh...chicks dig it
