First off, I believe the Vgod is a direct-battery, or faux hybrid, mechanical mod. It has no center pin in the 510 connector on the mod. Therefore, the ONLY type of atomizer (clearomizer, RTA, or RDTA) you can use are the ones with an extended center pin in their 510 connector.
Atomizers (example pics above) with an extended center pin (copper center) in the 510 connector (for faux hybrid or direct battery mods). This type of 510 connector is the only connector you can use with a hybrid-look, direct battery mechanical mod.

This is what can happen if you use an inappropriate atomizer on a direct battery (hybrid) mod. Please be careful with this mod; it is not for beginners.
Concerning the batteries, this mod takes a high drain 18650. Which battery you choose depends upon what coil resistance you plan to use. Judging by the mod you have chosen, I'm guessing you plan to be a cloud chaser, so I recommend the Sony VTC5A or one of the LG HB series of batteries for the most amps available.

I was using the original coils from vgod which is Nicrome fuse Claptons with 6wraps 3mm inner coil diameter. So I could be choosing the 30amp 18650batteries from one of LG or Sony.
I have a question about the mod deck, what’s the difference between the positive side and negative side? What should I be aware of when I going to build my coils into my deck? Btw, thank you for all the information you’re giving me.

OK, good choice on the batteries. 
I'm confused about your second question. Perhaps this video will help.

Glad to be of help. If you will be making your own, and you're new to making your own, start out with simple compressed coils. No need to complicate things trying to make exotic coils. Suggestions are in the blog post I linked last.
The more mass (metal) you have in the coil, the more it drains the battery, and the longer it will take to heat up the coil. I never understood why people make high mass coils with thick wire.
I should make it clear that I am not a cloud chaser. I never build lower than 0.6 ohm (dual coils).

I think I’m going to buy coils online or going to vape shops. If I going to vape shops to change my coil, what coils(dual coils) should I tell the shop to build for me? In order to be a cloud chaser, I like clouds hahaha and suitable for 30amp batteries of course
Well, since I'm not a cloud chaser, I'm not the one to ask about coils. I always believe in the KISS principle --- keep it simple, stupid.
No matter where you get your coils or who makes them, ALWAYS make sure that they comply with Ohm's Law. I've seen too many vape shop folks who make dangerous builds and don't even check the coils on an ohm reader. That is irresponsible and dangerous.
Owh the KISS principle, hahah nice tho!! I will ask them to show me the ohm reading of the dual coils, as long the ohm don’t exceed 0.15 should be ok.
Mechanical mods can have a difficult time with thick coils and claptons. I like thinner guage wire and small coils .2 ohms for them. I use heavy guage wire or claptons and higher resistance .4ish in regulated devices. I like having more surface area in those. The coils I use in regulated will barely get hot in a mech mod.
No, it is a re wrap erroneously labeled lesser quality cell ---> Bench Retest Results: Brillipower Green 3100mAh 40A 18650...preposterously overrated, not IMR
The battery(s) you need for safe operation depends on the resistance range you intend to use.
4.2v / .15Ω = 28a
The only cells that will support that amp draw safely are the LG HB (2,4&6) series & vtc3.
All will have miserably short run time at that amp drain.
You have it backwards, you don't want to go any lower than .15Ω, not exceed.
Actually it is always a good idea to leave a margin of safety below the CDR of any cell you use.
Some folks stay 50% under, some 20% below the CDR.
Is there a reason you feel the need to use such low resistances?

I wouldn't trust that cell with anything under .42Ω
I don't know where to source cells in Ireland
These might ship to your location
www akkuteile.de
www ecoluxshopdirect.co.uk
www nkon.nl
It isn't just the name brand thats is important, it must also be the correct model / CDR.
You'd be a whole lot better off using a high power regulated multi cell power device.

Then I wouldn't use it at all.
Yes , I understand, I read every word of this thread before responding.
The only way to ensure your safety is have & use the necessary equipment to accurately measure resistance, there is no other way to calculate amp draw.
Guessing isn't good enough.
Again, you'd be a whole lot better off getting a high power regulated multi cell power device & setting the mechanical aside.

If you cannot check the resistance of a build you shouldn't be using it on a mech. You cannot rely on "it came with the kit" to assure your own safety. Mechs require attention to the build and battery. If your can't test your build, put the mech away until you can.
There is no legit18650 40A That I have ever heard of. If there was it would be about 1000-1500 mah. My Samsung 15A are 3000 mah. And my 20A are 2500. I wouldnt subohm those in a mech. That is asking for trouble. Good advice I read here was Use batteries from companies that make good TV's. Samsung Sony LG...
