How do you know if you can sub ohm with it?

[MushroomFace]

I recently moved from an eleaf istick to an RDA. The RDA I have is a nemesis clone with a stillare atomizer. I'm on my 3rd coil build with the thing and the ohms are 0.36. This thing is awesome, it blows the istick away. So the other day I threw the atomizer on the istick and tried to fire it. It said "low atomizer" on the little screen. I've been looking at mods that use 2 18650 batteries, thinking of going bigger. My question is, how do you know if the mod will work with sub ohm coils. I'd hate to buy a cool new mod that has 2 batteries only to have it not fire the atomizer.

the nemesis is a mech mod. the stillare is an rda. the istick will only fire down to .4 ohms for the 30w i think 1 ohm on the original. most places you buy from will list the lowest ohm it can handle if its a vv/vw. if your buying a mech mod, the lowest it can handle is dependant on your battery

I see, the mods I was looking at had spots for 2 18650 batteries side by side. So is that also called a mech mod? I'm new to the sub ohm coil building thing but I think it's fun and the clouds are huge. I want bigger clouds.

a mech mod is something that has no electronics. just a battery and an atty. if it has a screen, if you can adjust voltag/wattage, its not a mech. i stick is a vv/vw mod. nemesis is a mech. what specifically were you looking at? if you let me know i can tell you what kind it is and if it has a limit

 

[MushroomFace]

Yes, I think I understand now. I was looking at all kinds, the ones with vv/vw and the mechs. The style I want is a mechanical box mod. I want to be able to go as low as I want, safely of course. The ohms law says with one 18650 you could go 0.19. However I'd feel more comfortable with 2 batteries if I went that low. Eventually I will need to upgrade. Thank you for responding, you've helped me understand the difference with the mods and now I know more.

you will also need to know if the batteries are in series or parallel. and you need a bettery with th proper amp rating. and .19 your pulling 22 amps wich would mean you need authentic 30 amp batteries here is a good list of batteries and thier amp limits

batteries in series will give more voltage. batteries in parallel will give more amperage. on easy way to check when you looking: if you have on battery with the positive side up and negative side down, and the other has the negative side up and positive down, thats series and will give you more voltage compared to amperage

the ivogo dimitri is a good dual parallel true mechanical box

Why do you need a mod that hold's 2 battery's ? Would 50 watts be good on a .5 build ? Have you tasted 70 watt's on a .8 build ?

I suppose I don't need a new mod that holds 2 batteries, I think I want one though. The reason being is that I want bigger clouds. With one 18650 on a 0.36 build I blow pretty big clouds. So wouldn't it stand to reason that lower ohms, enough to require 2 batteries to operate safely would produce even bigger clouds? I put the numbers in ohms law calculator for 50 watts and 0.5 ohms, it says 5 volts and 10 amps. It seems to be good but the 18650 I think is 3.7 volts, if you're referring to the istick mine is a 20 watt model. I have never tasted 70 watts on a 0.8 build.

What battery are you using for this 0.35 ohm build?

I don't think you understand mods, coils, and batteries well enough to be jumping into high-power vaping by getting a dual-battery mechanical mod. I wouldn't feel comfortable recommending any mech mod in your situation.

Riddle me this:
You have access to two dual-18650 mechanical mods. One takes batteries in series, the other parallel. You are using two fully-charged 20A Samsung 25R batteries.

For the batteries in series mod: You build a 0.35 ohm coil.
For the batteries in parallel mod: You build at 0.35 ohm coil.

Which mod/build combo provides more (ideal, not factoring in voltage drop) wattage? How many amps is each pair pulling, and is each build safely within the 20A limit of each battery? For each pair, what's the resistance that would cause the current drain of 20A on each battery?

I personally think you'd be better of with a high-power regulated device. Your 0.35 ohm build was probably maxing out around 43 watts, factoring in a fairly modest voltage drop. So anything that could put out even 50 watts would be an improvement, 100 even more headroom, and at 150 watts I'd venture to say that you'd probably end up with scorched wicks before megaclouds

That's why there is the IPV3 and others that are similar.

The battery I'm using for the .35 build are green sony 18650, I think they're 30 amp. I also use the purple efest and I understand they're 20 amp.
It's true I'm new to mech mods and sub ohm coil building however from my experiences so far the mech mod greatly out performs the istick .
I don't know the answers to your riddle. The guy earlier in the thread spoke of series and parallel batteries, I think the parallel mod would be better.
Megaclouds as you put them are my goal.

The answers to his riddle are all about safety. Learn to answer all of them or you can't safely vape a mech. Sorry, but it's just how it is.

Just an FYI, that istick 20 you have won't go sub ohm anyways so I'm a little confused by your comparison of it with a sub ohm setup. Now, if you had an istick 30 or 50 that would be another story since they would be capable of getting you close since they both can go down to .4 ohms. Just my two cents here, try something like one of what I mentioned or some other vv vw before getting into mech.... You may be surprised... ;p

 

[Das Auto]

That iStick 50 would be perfect for you, in my opinion! Sometimes I turn my Sigelei 100W up to like 70W on a 0.3ohm Dripper and its Way too much, burns too quick, gets my atty too hot and seems to waste juice! Makes great clouds at around 40 - 50W too.
I have a Sigelei 50W as well, I usually use my Subtank mini on that, with the 1.2ohm coil, but have used my dripper and it works Great!!! Rarely go up past 45W on it!
so that iStick would be great for ya! either the 30W or the 50W.

But again, if your really into the cloud chasing, go with the 150W + Mod box from Sigelei, that will give you more then enough headroom for all your cloud chasing desires!!

Just clearing some things up here, no offence to you chadelliott then.

iStick 30W: Minimum ohms: 0.5

iStick 50W: Minimum ohms: 0.2

DNA 40: Minimum ohms: 0.2 but some peoplle are able to fire 0.15 ohm builds with it also

This is ridiculous. You are not going to find your answers with your little to no knowledge on how ANY of this works in this thread asking what you are asking. There are a few options here.

1. Do research very thoroughly and learn the difference between a mechanical mod and a regulated mod using search engines and forums by READING articles written by the people that do tests and explain what your exact questions are.

2. Keep trying to compare things that are in no relation to your desires.

3. Ignore everything buy a dual battery box mod, blow face off.
