Really Sub ohm mod

Status
Not open for further replies.
I am new to the forum here but have been lurking for a while. Anyways my local vape store set me up with a mech mod and a dual coil setup.I have a smok Smoothe with 18650 sony battery and Igo-W4 dripper. I am vaping 100% VG juice. However my RDA with 2 coils is reading at .24 ohm. From what I read most wont go below .7 and that is from the Vets on here. Now the rebuildable guy in the store says this is perfect for the Igo series. I don't really care about cloud chasing just wanted to get into mech's. However after reading I am at a really dangerous level. Its a cheap mech mass produced but should it be that low?

Well just coming from my own experience .24 ohm is insanely low, and your B&M has no business putting that into the hands of a new mech user. I've been vaping for a year now, and when I got into the sub-ohm thing I was building for .8 ohm, and lately have settled into .7, which is as low as I need to go. Tell me, did they educate you on how to build this rig, how to check for hard shorts, and correct ohms, how to check where you battery is at, or did they just build it for you and turn you loose with it?

On a mech you can go that low, but there's really no sane reason to do so. It's entirely unnecessary, drains batteries much faster, and if you don't know what you are doing can get you a nasty case of thermal runaway, and you really don't want that. If you have not already done so I'd strongly suggest you do some homework on sub-ohm vaping and mechs. I'm sure others will add to this but if I were you I'd start by getting an ohms meter/multimeter, a battery checker, and make real sure you have the right high drain batteries, then do a lot of reading on this. Also, YouTube is your friend.

Exactly this, completely irresponsible to build this for you without checking that you know the dangers. On the plus side the battery you have (VTC4 or 5) can handle the low ohm rig that you have.

That's just poor judgement. The fact that this B&M would just hand you a build like that and not even explain the risks, and what you need to check for etc....

That just blows my mind.

Yes, mech mods can definitely handle build like that, but there truly no reason to do so unless you are cloud chasing (which is a whole different conversation).

You are doing the right thing by doing your own research. There are probably other people that the store sets up like this that won't be so lucky...
 
Ok so i have immediately taken off the dripper and placed my nautilus on there just because it gives a good flavor and cloud. The shop showed me how to build a coil and that they need to glow from the inside out and that was it. All i know for ohm is what I have read. I use a multimeter to read ohm and my coils are running at 1.2 that I have made. So i think i will just stick with this. Thanks for the info. Really saved my .... there.

Good on ya! I think that's a wise move. Find out for yourself what resistance you want to vape at, you might not even want to go sub-ohm to get the vape you want, rather than let some careless vape shop nerd decide for you. Learn how to build for the vape you find satisfying and stick with that. It might not even be sub-ohm, many are very happy at 1.2 ohm and above.

Good idea. If you're building 1.2 ohm coils, those should be fine. A single 1.2 ohm coil will give you an almost 15 watt vape, which will be a pretty nice step up from your nautilus and well within acceptable safety ranges. It's a good place to be while you're getting your practice in. Over time, you can gradually drop the resistance a tenth at a time if you want more power, if you think you'd enjoy more power.

But yes, .24 is not where you want to be unless you understand exactly how it works and understand the risks.

I'm so glad you are being safe and smart. As I understand it going that low can be really hard on the battery and it will vent then if it can't properly escape that's when you get a pipe bomb. Very simply put but you get the point. I really am shocked that a shop would do this. Perhaps you should have a word with the manager and see what he thinks about this? I'm pretty sure he or she won't be very pleased. I'd give them a call. You just might be helping out someone else by stopping this employee. I'm sure the manager does not want that kind of liability. They need to be made aware of what's happening in their shop.

I agree Any shop who would just put something like into the hands of a new vaper needs to be closed down. My venture into sub ohm was to .7. lately I have been playing in the .2 area just to pack my lungs with nice warm vapor. I'm not really interested in cloud chasing, but its a product of low ohm builds. I have only been vaping for 9 weeks, but I have read literally hundreds of write up on low ohm builds as well as watched pretty much every youtube video on the planet. My big strength is I am very good with electrical devices and electronics so that's a big help. Don't be afraid to venture into the sub ohm end of vaping, just properly educate yourself first. Being a member here is one big way to get that info

I need help!! I have a cool fire 2 grenDe mod with an iclear 30b tank on it. I have replaced the head in it multiple times but after chainging it last night it will not work. It turns on when the buttton is pressed u can feel the coils heat up but it will not produce any vaper. I even tried two different heads. Whats wrong?!? Help me!

did you put juice in the tank? if it is heating the coil and juice is present, you should be getting vape. What setting do you have the mod set to?

your running 17.5amps with that build at 4.2volts, but with volt drop your looking at less. Your batteries ,if they are the vtc4 or 5 will have a 30amp continuous rating. As long as the build isnt shorting you will be fine with it.

When I started sub ohm I built my coil at .7 and now settle around the .4-.7 range depending on built. I have tried a few .25 builds and while they were nice, they really didnt do anything my .4+ builds do besides drain the battery faster.

Honestly your shop sounds better then some other on here, at least they set you up with the right batteries for the build they put on it.

Since your new, did you buy a multimeter to check your battery life? Also do you plan on doing your own builds?
