Fasttech Dual Battery Mod??

Why is the iStick Rim sold at Fasttech different from all of the reviews I've seen? It uses a removable 18650 battery and the USB port is in a different position. Here is the link $51.18 Authentic Eleaf iStick Rim C 80W VW APV Box Mod + MELO 5 Tank Kit - 4ml (28*21.4mm (OD*ID)) / 0.6/0.15ohm / 1-80W / 1*18650 / 28mm diameter at FastTech - Free Shipping  

Hello guys,
I recently purchased a single coil RTA, my first rebuildable experience. I love it!! .
I saw at the shop a double coil RTA and a Double coil RDA, was planning on buying one of them until I thought I only have a 100W mod. Do you guys think it is enough? Are there some specific ohms coils that could make it work etc? Or is a 100W enough? I am new to this so calculating ohms law and all the other stuff I will learn, I just need a answer from the double coilers if you guys use higher wattage mods or not.
Thank you in advance!  

An online vape shop here at Greece at the description for dotBox Dual Mech mod says"

"Switch to Parallel Mode for longer Vaping time and exceptional power from two 18650 batteries".

The dotbox dual mech has the option to select series or parallel connection via a switch.
I send them a email that this doesn't apply (for the same power output always),for example 0.1 ohm coil in parallel connection and 0.4 ohm coil in series connection.

Two batteries in series provide the same amount of watt hours a parallel connection does.

The vapeshop replied and told me that the description is copy and paste from Dotmod.com

Indeed.

"Last Longer. Switch to Parallel Mode for longer Vaping time and exceptional power from two 18650 batteries".

The vape shop also said that the voltage sag at parallel connection is spread out over the two batteries in Parallel.Thus more vaping time than using a series connection.

Okey I made the calculations for voltage sag using for example two Sony VTC5A 18650 batteries with a DC Internal Resistance = 18.6mOhms (0.018 ohm).

I got the same voltage sag 0.378 V in both configurations (0.1 build in parallel-0.4 build in series).

Am i correct or am I missing something?(i'll send to the vape shop the link for this thread so they can read your opinions because i think they believe i'm talking bulls..t!  

So I'm in the market for some high drain 18650 batteries and I was about to go with the Samsung 25R but then I stumbled apon the AWT IMR18650 2600mAh battery. I'm see in some places that this battery have a maximum continuous discharge of 35A and a max discharge of 40. Is this really true? Because I'm also seeing in some other places that it has a maximum continuous discharge of 20A and maximum discharge of 40A (which seems to be a bit more believable to me). If anyone has a link to some testing done on these it would be greatly appreciated. Thanks!

Here's a link to FastTech's listing where I originally found out of this battery: https://www.fasttech.com/products/2287804

And a Ebay listing saying it has a Max. Continuous of 35A: 2 PC AWT IMR 18650 Li MN Battery High Drain Rechargeable 3 7V 2600mAh 40A Yel | eBay

Anyone on here know where I can get a custom box mod made for me. I want the option to be able to vape in watts and voltage and I wanted to be either a double or triple 21700 mod. If anyone could help me I would appreciate it.

Well, hello again. I know I made 3 posts in 2 days and please tell me if it is bothering you

Do you have any 3D printing vaping related ideas?

Oh by the way haha I want to share a little story with you, don't read it if you don't want to

So I woke up one day and said to myself out of nowhere;
"Ima flippin vape"
I had no experience in vaping at all at the time, but I could at least do some stuff in engineering. (I'm double licensed in electronics and mechanics)
So I lit up a cigarette and began designing the body of the box mod. I had no idea how I was going to make it but basically, I was going to print the whole thing, including the atomizer (RDA style, I didn't even know it was called an RDA haha) but I had no resistance wire. So break the hairdryer, I did.
After a hell lotta designing and stuff, wrapping the wire around a piece of cotton, (yup) hooking the battery up, but... well... it was a drill battery, I'm talking about 12 volts.
I then bought some glycerin (100% VG) from the pharmacy, and all I was looking for were them fat clouds. Oh man, fat clouds did I get. But also the first vape hit in my life was a dry hit.

After coughing my lungs out, I looked at the cotton, obliterated it was.
Instead of reducing the voltage, I just threw like 10 more windings to it and since, it was the best vape I ever had somehow, ooh I also bought some flavouring and it just tasted like I was eating the real thing.

Then the plastic melted  

Wismec 3 Battery? No good. Breaks within a year without dropping. Replicated on two mods.

Wismec 2/3 mod? Yet again, poor manufacturing. Wires not soldered properly. Almost lasted a year.

Squid Industries Double-Barrel? Craps out after 1 month without any damage. Wont turn on.

GeekVape Aegis Legend? 2 months and not reading the batteries right. Never so much as tipped over on my desk.

SMOK? Had more than I can count or bother to recall the exact models, but every one busted within a year.

None of them seem true to their warranties either. They make it as tedious a process as possible. I haven't tried with the Aegis Legend yet, but I'm going to go out on a limb here and say it's probably more of the same.

At this point, I am convinced that I have spent more money on mods than I have on juice. These mods are all made like crap. I don't want to spend $80 every few months to get a new mod. I just want to vape for gods sake.

Has anyone had a mod that has lasted them over a year? What kind was it? I've asked this before and that's what led me to the Double-Barrel and the Aegis Legend. Both have failed on me even sooner than my previous attempts.  

So I just placed an order for some vape gear on Gear Beast. Been eye balling their site for a few weeks now.... kinda seems like the new fasttech in a way. I've ordered from fasttech many times. Their shipping was actually quite fast when they first started selling vape gear, but that went down hill quick as they got more popular.

So I'm wondering what kinda time line I'm looking at for a west coast USD delivery of my purchase. I figured you guys could help me out as I'm assuming a few people seeing this post will have ordered from them before.
