Wow, was constantly vaping on 18350 while viewing this thread, guess ill have to switch to 18490. thanks alot people!

Considering there were only 4 posts by the time you put that up I fail to see your smarmy point. Oh yeah - I do. If you were expecting something less than credible advice on this one you came to the wrong place.

yes that is dangerous. i believe the amp limit of your 490 is right a 8.8 or something like that. that is almost 100% the amp limit. and like i said earlier i like that be at about 50% the amp limit just for good measure. you are stressing that battery and will not get the performance you should and the life of the battery will be shortened. as well as the possibility of thermal runaway. and i will say it again. if you are going to go below 1.0 ohm i would get a good 18650 with an amp limit of at least 20 if not 30. that way you could run any coil you care to run. maybe not 100% safe. but way, way safer that running it the way you are now.

Vaping with aw imr 18350 at 0.78=.8 ohms, battery gets warm. any advice tips? Running on private v2 clone and chimbus with 28ga 3mm ekowool

You can't use 18350 batteries with sub-ohm coils.

Please read more about battery safety and coil rebuilding in general before you attempt to do it. It requires knowledge and skill.

In the meantime, may I suggest switching to a safe battery like an eGo or a regulated mod like an iTaste MVP and a good clearomizer? Kanger BCC makes really nice ones--and you'll be safe!

Fifteen C? Really? Are you sure than isn't one-point-five C for an 18490?

yes 15c.

IMR18490 Specifications :

Nominal Voltage : 3.7V
Capacity : 1100mAH
Lowest Discharge Voltage : 2.50V
Standard Charge : CC/CV ( max. charging rate 3A )
Cycle Life : > 500 cycles
Max. continuous discharge rate : 15C
Operating Discharge Temperature : -10 - 60 Degree Celsius

15.c = 16.5 amps continuous

taken from AW dealer

IMR16340 / IMR14500 / IMR18350 / IMR18490 / IMR18650 / IMR26500 *Part 2*

some places listed it incorrectly at 8 amps. check my above link, it's really 16.5 amps(15c)

What? You're firing at me because im asking a questions here? This is a forum whereby i can post freely without your judgement, since you're very experienced*, please do not bother about me asking a nonchalant question here. Its solely for safety purposes for a newbie like me.

@katya

I did my research on battery,coils before getting on hand of these. Theoretically, even at 4.2V at 6A, it will keep me at 0.7ohms limit,dropping it to 3.7V will get me 0.62 ohm at best.. running at .8 ohms and having it warm is the question i wanted to ask you guys.

I've switched back my 18490 since its done with charging and running well, thanks for the tips. And ranting :)

i checked out your link. but i also did some research of my own and i have read that it had an 8 amp discharge i have also read that it had a 10 amp discharge and have also read that it had a 15c(16.5) amp discharge. i wasnt able to find a website that seemed 100% legit so i cant be too sure. if i were you i would be really careful. and it may be that it does have a 15c discharge in which case you should be good. but i would check the battery and make sure that it is not getting warm and that it is performing the way that it should. i just want everybody to be safe. it only takes one person to have a battery explode in their face and they could ruin it for all of us.

Appreciated the updating. Well, assuming 18490s at 4.2V with a discharge of 8A, its .5 ohms at minimum. So keeping up with my coils, so not land me anywhere near the dangerzone. ^^

that is still what i consider "in the danger zone". like stated before. you only want to push 50% of the amp limit. meaning. you wouldnt want to push more than 1.0 ohm through a battery with an 8amp limit. this will give you the best lifetime of the battery and not stress it as well as keep you safe from a venting battery. i cant tell you what to do. but when/if something goes wrong. we all told you that, that was not safe.

Batteries are cheap, Skin grafts aren't.
I am a big time sub ohmer, and not really for any other reason then its the way I like to vape to help me keep off the cigs.
What I mean by that is I like to take shorter drags the same as I did cigs, long extended drags make me feel frustrated with vaping.
So I sub ohm to get the vapor production I enjoy. I usually run between .2 to .3 ohms on a 18650 rated 2100 or 1600 mah, with a 30A high drain. "the green sonys" I dont even mess with any other batteries.. I may try some MNKE in the future but I won't use anything under a 30A limit.

One really has to not only know the laws behind it, but they need to be aware of the strain they are creating in their device and when to stop and let it rest or pull the battery out. even if you think you may be in safe limits does not mean you still can't get a runaway depending on how you may be vaping.....and vaping blindly is not a good thing. know your specs , know your build , know when to stop.

if you get in tune with these things you will be ok.
but ya got to be aware of what you are doing and how you are doing it.

Have the tools you need to also know what your limits are even if you believe you are playing it safe.. its good to know where you stand...

1: know the limits of your battery
2: get a ohm meter for your build to know where your build is at..
3: use the calculator>>> Ohm's Law Calculator

;-)
