So I have built a 6 wrap 1/16 drill bit and it comes at to 0.25 ohms so I plug the numbers on a ohm calulator and it comes out to 19 Amps okay cool the vtc 5 can handle 30 amps but what concerns me is that it says I will be using 90 Watts! Should I be concerned? Is vaping at 90 Watts safe? I have not fired it up yet just want to get the green lights here first
should I be worried?

I'm not into rebuilding or anything, but my thoughts are if you have to question it, then yes, you should be worried. I know that with rebuilding especially when doing sub-ohm stuff, you really must know what you are doing.
If you have to ask "should I be worried?" then I would recommend you do some more reading about ohm's law and safety, etc. I am hoping my post will give this thread a bump and someone who is more experienced will pipe in with practical advice.

Disclaimer: I would NEVER consider vaping at that low ohms
What is the voltage drop on your mech. If you do not know then don't fire it. That could easily take things to the extreme/dangerous point.
As far as vaping at 90 watts I got no clue. I wouldn't do it

90 watts is going to be very hot and intense. Lowest I have gone is a dual .35 ohm coil wasn't a fan

1: "Should I be concerned?"
Yes.
2: "Is vaping at 90 Watts safe?"
From a little 2 ounce battery? No.
That's why you have to be picky about the battery in the first place.
I=V/R
I=3.93/0.25
I=15.72A
P=I*V
P=15.72*3.93
P=62W (rounded up)
I don't know what ur voltage drop is exactly, but at 3.93V, I only get about 62W.
Now, that's not to say ur safe, just that 62W is far less than 90W.

Watts are just amps multiplied by voltage, so are directly proportional to amps. The batteries aren't rated using watts, since they have a (relatively) fixed voltage.
As mentioned, voltage drop elsewhere in the circuit would likely reduce your estimate. Anyway, I would not feel comfortable pulling ~19 amps from a cell supposedly rated for 30 amps, nor would I want a ~90 watt vape. I would certainly research the battery in question well, to get a better idea of what their test methods were, and how that compares to worst-case usage, in my application. I prefer a rather large 'buffer' between demand and limit, personally.
U r very likely I under 4.7V. But who am I to say. Where did u get the number?

73 Watts without a load not actually what you will be vapeing. Either way .2 is hot as hell even on a near dead battery it won't be enjoyable unless that is what you like. I still have to ask what gauge are you using it seems very low resistance.
edit: If you are absolutely sure your sony VTC5 is real you won't vent. If you bought from some dude on the street I would not fire this.

You are right, the VTC5 can handle that. Here are the unknowns. There is debates as to heating e-liquids at high temperature, one of the worries is that it could break down pg or vp into toxic and carcinogenic chemicals.
Depending if you have 1 or more coils the heat generated by your atty will differ. If you have single coil, all of that wattage is going to heat up only one coil, generating a lot of heat, if you have 2 coils the wattage will be distributed over those 2 coils... generating less heat.
If you want to go that low (Which is pretty low.... why not bump it up) have more than one coil to reduce the heat generated.

Where did you get 4.7V from? That alone tells me that you should probably research a bit more before moving forward.
What is the voltage drop on your setup? How have you tested it? Under load? What resistance coil did you measure it with?
As long as the wick can handle it and stays soaking wet(SOAKING WET) the build should work.

I run my Omega quad coiled at .67ohm and it gets real vicious if it gets close to dry.

Uh huh.
Should you be worried? Yup. Most of the counterfeit batteries made are sold on EBay, Amazon, and Alibaba. Unless you purchase your batteries from an authorized and trustworthy e-cig vendor you can't be certain if you buy genuine name brand batteries.
