My first build!

[DuexDrei]

Hi All, just wanted to stop in and say howdy, been vaping for roughly about a year, and withing the last month i graduated from a cheapy Tsunami, to a mini protank 2 on a vision VV to a MVP 2.0, and then i discovered the joy of "cloud-chasing" ran out a few days ago and bought a mech mod (chi you) and a trident rda, the trident came built with a 1.7 ohm setup so i enjoyed that until i finally got all the tools to do my first build!

I just completed it and man its hits like a truck with clouds for daaaays, so happy.

i wanted to see if i could get any feedback on 2 things:

1. any advice on my wick set up? (see pic, i'm using organic cotton)

2. my build came out to be a . 4ohm, a little lower than i was shooting for but if some one could double check my safety match for me that would be great! i'm using a VTC4 so 3.7v at .4ohm = 34.225w. It should be safe to hit on that right? i've done alot of reading on the safety aspects of this but i would value input from anyone with more experience or knowledge than me!


Thanks for the awesome forum, and vape on.

Should be about 9.25 amps and within the rated capacity for the battery you are using. I can't see a picture so can't comment on your wick.

NB: I do however advise you to stay above 1 ohm builds until you have a bit more experience.

Instead of checking it for you, I'll do one better - I'll tell you exactly how to know FOR SURE yourself. Once you run through it, I'll be happy to double check your math.

First, you've already tested your coil. Excellent.

Now, you need to go look up the maximum continuous amp rating of your battery.

Take that number and multiply it by 0.75. This is the highest you want the amps in your build to get. It's your upper limit.

Now go to Ohm's Law Calculator. Plug in the voltage of your battery at full charge (4.2v) and the resistance of your coil (0.4ohms) and hit calculate. Now look at the current. Is that number under the upper limit you calculated above?

If the answer is yes, your battery can handle that build. If it's not, it can't.

However, that doesn't mean that YOU can handle that build. Building sub-ohm coils before you have learned to build consistent and reliable coils in a normal resistance range (like 1.5-2 ohms) is not the greatest idea. You have very little margin for error when you're sub-ohm. You don't want to go through the learning process at sub-ohm resistances where mistakes can be dangerous. Better to learn in a range where mistakes are not as big a deal first. It's just about impossible to learn anything new without making a few mistakes. Building sub-ohm coils is working without a safety net. Make sure you've got it down cold with the net first.

Your first build should not be .4 ohms.

Thanks Singaw!
I added the pic , cuz like a newb i forgot to the first time. lol

Any particular reason you advise to stay away above 1 ohm? If i have proper equip, understand the safety and enjoy the sub-ohm vape is there anything i am missing? just wondering.

Thanks for reply and advise, BTW i will prob do a build next chance i get i'd like to be in the .8-1.2 range as my lungs are not used to massive vapor clouds yet. i rarely use the mech mod/rda its just my at home recreational use mod, i vape on the aerotank/mvp 2.0 95% of the time mainly because i cant drip while driving/working which is where i do my most vaping! (on that note, i tryed the Kraken RTA thinking i wouldnt have to drip it nearly as often, but found that not to be the case as it burnt my cotton after 3-4 hits within 5 mins, just didnt seem to wick up fast enough, and the guy at my vape store built that one out for me at a .6ohm)

I can see the picture now and looks like about 4x more cotton than I use but then again I am not a cloud chaser and build my dripper with .9 ohm double coil. I think you are doing well for a beginner but good idea to take novamatt's advice to heart.

 

[DuexDrei]

Thanks novamatt,

I understand what your saying and agree with you 100%.
Just so we are all on the same page, i'm not just walking into this blind i was taught to build buy a guy with 2+ years of hardcore vaping and i made sure to do my research before i shelled out almost $200 for my mech mod, RDA and the supply's to build.
That being said i value your input and as stated will rebuild up to around the 1 ohm range, if for no other reason than to error on the side of caution.

Thanks Guys!

(VTC4 Maximum Rated Continuous Discharging Current= 30A x.75=22.5A, 4.2v Maximum Charge Voltage and .4ohm puts me at 10.5A well withing the acceptable safety limitations of this battery. Thanks!)

You're welcome... we all mean well but sometimes it just doesn't come across that way. We deal with a lot of people who go from vaping on a ego for a few days and then deciding they can make .25 ohm coils and run it on a 18350 when they don't know the difference between a volt and watt. I wish my first build looked as neat as yours and glad I didn't take a picture of mine. lol

 

[DuexDrei]

I never do anything dealing with a battery inches from my face without doing as much research as i can lol seems liek a good rule to live by.
That being said, where i do lack the experience is more along the lines of flavor maximization which is what i'm after more than "cloudchasing brah" lol do you find a better flavor around .9 ohm higher or lower? more or less cotton? and are the crazy builds such as "diamond" "octopus" "dragon" going to get better flavor than a standard dual micro coil build?

I really appreciate everyone's input thanks for taking time to help the newcomers like myself!

 

[Singaw]

Flavor is very subjective topic. I find a .9 ohm dual vertical micro coils works great for me and when I found that combo I stopped searching. I use very little cotton, just enough to come out the top of the coils and a little to wick off the deck. I don't have the time or patience to make some of the more exotic coils but have tried a few and didn't notice enough difference to change from my tried and true setup.

(Raising hand) I barely know a volt from a watt. But I'm building coils in the 1.6-2.0 range, and rarely turn my Sigelei past 9w; in fact I don't think I've gone over 9w since I got a kayfun, it hits so great it doesn't need all that heat. But I do love stacking '350s, they last me 2+ days that way, but I made sure to find out as much as possible about doing it safely -- hi-drain, paired sets, always charged and used together -- eFest IMRs. These things hold a lot of stored energy, and I really don't want that energy directed at any part of my person, and certainly not my mouth/face or hands.

One thing I was wondering, on that subject -- yesterday the pair I was using got down to the level where the Sigelei was telling me "low voltage", so I took them out and put them in the charger, where they seemed to charge quite normally. I didn't damage them by letting them get that low, did I? I really hope not, haven't had them all that long.

The protection circuit in your mod won't let the battery go below 3.2 volts. You're fine.
