ABCToy4Me on Amazon has VTC5s. Very fast shipping too. I've bought VTC3s then VTC5s from them.

Thanks Bearded Man - I ended up struggling to find anyone to post batteries to the UK, so I found a supplier in the UK but only had one battery - so bought it and then of course found another supplier overseas with plenty of stock, so bought another 3 :)

That's a nice looking mod. Never seen a copper nemmy with brass rings....makes me want to pick one up as well lol.

Right now I have 2 KFL+ both with twisted 28awg wicked with cotton
1. running at .52 with a 80%VG 20%PG (a friends DIY Banana Cream Pie) NOTE- it is only at .52 because I was experimenting with twisted wire and have been too lazy to rebuild it ha ha ha
2. running at .72 with a 50/50 blend (GrimmCreations Song Bird)
I prefer higher VG mixes as I drip mostly and tend to have reactions to PG when vaped all day (throat irritation and sometimes headaches) , the Kayfuns are for on the go vaping. I don't DIY but after my friend started to, I may be picking up some supplies.

The one at .52 ohm was drilled out to 3/32 (2.38mm) at one of my local B&M's. They used a drill press and drilled it 2 or 3 times each time getting progressively bigger until the desired size was reached. Would have done it myself but I don't own a drill press. If you have a hand drill and a sturdy table vice, you should be able to do the same. Just be careful

from looking at battery graphs and cross referencing, it looks to me there might be 3 big players in the sub ohm category that rise above the rest.

key features are voltage drop during a load test and usable capacity above 3.5 volts with special note to cell temperature.

there's the samsung 20R 20 amp battery. while only 20 amp rating, this thing seems to be the benchmark in voltage staying power and usable capacity under high loads.

there's the purple 35 amp efest. this thing seems to stay right up there in the top 3 and probably should be considered the #2 sub ohm battery.

then there's the sony vtc5. sonys newest installment to the high power 18650 lineup looks very promising and produces graphs with staying power on par or exceptional when compared with the other two. however, there is a special note that under a 20 amp load, the vtc5 heats up hot and fast.

for sub ohming all day, may i suggest a Reo Grand & Reomizer 2.0 or LP Reo Grand and nearly any RDA you can modify for bottom feeding? gives you the best of all worlds. compact, takes 18650 batts, uses an RDA has on board juice capacity to last all day and frees up one hand since you don't need to drip from a bottle for every few hits.

Hi Numbskull

I actually went for the SS with Brass rings - this one and the copper and brass are both super custom as it requires breaking down of 2 Nemmies to make one :)

So I was wondering how the KFL+ was drilled out being adjustable and all - and does the center hole still restrict air relative to where you had it drilled on the side?

Hi Beckdog, thanks for all that info...I have already bought the mech mod (nemmie clone) and batteries (x4 Sony VTC5's). I have also bought another atty and also dislike dripping. So I am wondering at this point if i need another new RBA to get a decent vape around 0.5 ohms.

I am interested in your comment that you can vape all day using an RDA without the need to top up the juice, by modding the RDA to bottom feed. Any suggestion as to which RDA to mod?

some links to give you an idea what's available. you can also search to see what others have done. some have drilled vertical holes in positive pins and holes horizontally along the RDA base for drainage. some have mad channel along positive pins. others have just cut the insulator for the positive pin to make a channel for juice to flow. it will all depend on the atomizer and your tools and ability.

you should come to the reo forum and poke around a bit and ask some questions if you're interested... Reos Mods

there's a good group of people over there eager to discuss anything you're interested in pertaining to bottom feeding and reos.

Cheers for the info Porkchopbun. How would I be able to ascertain if a mod does not have a spring? Also RE batteries can you have button and flat top batteries ? Finally, could you recommend a decent dripper ?

Thanks !

Phil

Don't worry about the spring. Get a good battery (the Sony 30 amp battery is the standard) and vape away.

I wouldn't use a Kayfun for any kind of serious subΩ vaping. You can do it, but you'll be better served with a dripper for that.

I would get a starter dripper like the Igo-L from a vendor that will drill the air hole out. 1/16" is fine, some like it larger. If you find it's your thing then spend the cash to get something better.

the floating pin keeps me sane.

All mods should have a floating pin, and clones should start using them whether they are in the original or not. I have a MOD that I generally love, but the pin is so finnicky that sometimes I want to throw it against the wall. Put in a floating or spring positive pin, let it sit high and don't make me sit there and fiddle all damn night.

^I just like floating pins to keep mod flush without always taking cap off. Not only does it look better, but it keeps the tiny threads of a 510 safe..but all mods should be based on the 4nine. I love mine. Very simple, but a big step in the right direction for what should be in a mod.

Most people say the vape is too hot on a Kayfun at sub ohm though, whereas others have more airflow or allow modding the airflow

I've found that for me, anything below about 1.2Ω is too low for my Taifun GT (Hcigar clone), likely because of the restricted airflow. I have one at ~1.05Ω right now, and it's WAY too hot for me.

I haven't run any of my Kayfuns lower than 1.4Ω yet. Currently I have 3 running - 1.4Ω, 1.5Ω and 1.7Ω - and all of them vape fantastically, though none of them would be considered vape chuckers (which isn't to say they don't produce a lot of vapor). All three also have air flow control (I have Hcigar KF 3.1 clones).

When I want to further explore the world of subΩ vaping, I'll use my dripper. Currently I have a single micro coil running in an Igo-L (with drilled out top cap) at .9Ω and a dual micro coil running in an Igo-W at .8Ω. The Igo-L on top of my Sigelei 20W is easily the best vape I've had yet.

Hi numbskull

Thanks for the congrats :)

I decided to go for a custom nemmie clone - SS with Copper Rings: Custom Nemesis

I am now in two minds if I should just go with the KFL+ and build 0.8 ish or buy another atty for 0.5 builds. Like I mentioned the post is not trustworthy in Thailand, so If I don't buy an alternate now then I aint getting one.

I also need to mix my juice different to cool the vape, I will be reducing my PG from 80% to either 40 or 30% - and if i can source it, also adding Saline at around the 4% mark. What ratio's are you mixing / using for your 0.7 build??

Phil

I would get that KFL+ and start with builds at around 1.5Ω and then gradually move down. You'll find that it produces WAY more vapor than any tank you might have used so far. It's not going to chuck clouds, but it's no slouch either. I wouldn't get ANY atty and immediately throw in a .5Ω coil until you know what you're doing. It's all about finding what you like through experimentation, not about hitting some magic number.

I think i will try and see how i like a 1 Ohm dual coil, but with high VG. I am new to dual coils and always vaped high PG, so I am quite used to a decent throat hit...I have vaped single coils at 1.5 Ohm and high PG. If i make it 1 Ohm i can fire it on my Pro Vari and kick the voltage down if it is too hot eh?

I think i might chuck in the towel and order a RDA to be on the safe side...BUT i must be able to have some sort of reservoir so it will last all night with no topping up at all...any suggestions on which RDA would be suitable?

Hey Beckdg thanks for the links i am looking through them now. However RE box mods, I have interest in the soon to be released Hcigar Hana Mod..looks very nice and has 30 watts. What do you think of this mod?

I have heard from multiple sources that the Kraken RBA is fine for sub ohm builds - It also looks awesome so I might get one of these for my sub ohm dual coil build. Also hearing that it produces better flavour than an RDA....?

EDIT: Ok so i bought a Kraken. I plan to build a dual coil 1.2 ohm Kayfun + for pro vari...and then set up the Kraken in "auto dripping" mode, dual coil 0.7 ohm on my Nemmi mech. See how that goes.

It's not only about throat hit. There are things about building, juice, etc that you will want to learn through experimentation. For instance, you wouldn't want to throw in any more than 3 or 6 mg of nic with one of these cloud chucking machines because it's simply too much for the vast majority of people to handle. Also, you may have a hard time with your Provari at 1Ω. It might fire, it may not, or it may do so intermittently with various warnings thrown in. There is a 3.5 amp limit on the Provari, which greatly limits your ability to go too low. Besides, the Provari was designed to vape HIGH resistance atties at higher voltages. They recommend 2.5Ω and higher!

As I suggest, I would start at about 1.5Ω on your KF+ and work your way down from there. I absolutely would not grab my brand new Kraken and throw a .5Ω dual coil, having never built one for any device. Start at a reasonable resistance, then move down as you feel is necessary.

Hi BlueGrassTubb

I have heard that 1.2 Ohms is the "sweet spot" for a Pro Vari, as it allows 14.7 watts and 4.2 volts (although not sure you would want that much wattage) - Currently my choc juice seems to taste nice around 8.5 watts, but not tries it at 14.

I wont go 0.5 Ohm on my first build, noooooo. But will be aiming for a 0.7 build. You are right about experimenting with diff juices - I already have a separate thread discussing DIY for sub ohm rigs. Long and short is much more VG with distilled water / saline. I am currently on 6mg juice - so as you suggest i will halve this to 3mg.
