very SLRs ohms (<0.5 ohms), ss wire wick rope, & a-1 kanthal ribbon wiring

[donneee]

hi guys, i've been vaping for year and some change now. got into rebuildables as soon as i found out about them and then got into gennys after the aga craze and finally upped to an ac9 after falling in love with my rsst... so i guess i'm fairly experienced.

my main question to you fine folks now is how low can one go before it gets dangerous? i'm pretty sure i have a lower then .5 ohm ribbon wrap on my set up. i find it heats up way faster then just adding one wrap, flavor is okay (juice i'm using is something i'm not familiar with) and i made sure all shorts and hot spots are gone as well. i've yet to put it on the multimeter cause it's 2 in the morning, lights are out, and i finally got it going right. ~_~

here's my scenario:
no issues in wicking (7x19 s.s. wire rope is amazing), no "burnt" taste to my knowledge. just an okayish vape. okayish because i know i'm using an 18mg liquid and it should be giving me one hell of a throat hit........ but it's not there? is that right? it's puzzling me. it's as if i'm vaping 8-12mg liquid. with a 3-2 wrap it's as if i'm choking, but no vapor, and with a 2-1 wrap i can cloud up my room but little throat hit

anyone else with ribbon wire experience have experienced anything like this? how long does a 3-2 wrap take to heat up for you? my 2-1 wrap takes less then a second to heat up to optimum tempurature, but when i do a 3-2 wrap, i have to hold it for 30 seconds or so, and like i said before it won't make as much vapor as my 2-1 wrap. how "tight" are your wraps? how many wraps of mesh do you have on the top of the wick? yay/ney for ribbon wire?


meh, ribbon wire is a pain. any info/help/tips would be very helpful


thanks!

your battery will give ya an indication of its danger by heating up in your hand.

I get exxcellent vapor, th, flavor, with higher ohm'd coils. but if you like charging batteries

 

[donneee]

i don't mind changing batteries, i have 2 18350s on my as back up at all times, a few 18650s charging, and a few other batteries laying all over the place. i did one day get tired of it, vaped a few things outta my vapebox but i just couldn't use carto's, atty's, silica wicks, and pourous ceramic as my wicking material anymore, it's just not the same =\.

the batteries don't heat up as much as i thought however... but i literally only get about 2 hours worth of vape time from an 18350. more or less~ i guess as much time as it says on the battery-2.6w/h hahaha, so i try to use it sparingly and it satisfies me time and time again. unless i'm chain vaping... then it just gets warm. i've learned not to touch the top cap when i use this thing lol

 

[Kevin Brown]

you really messed yourself up there, nothing will hit like what you done to yourself.

just go ahead pick up a tig welder, then, aha then, you' be there

that will get ya low enough

I've used .8mm ribbon at .7 ohm on FC2000... and true, the vape is mellow. huge clouds tho! but almost no hit.
try some 25 or 26 gauge you may like it better if you want more hit.

 

[donneee]

i forgot to mention i am using 0.8mm ribbon wiring. i might try normal 26 awg normal kanthal again since it's easier to work with. but the subtle difference i can notice. then again i haven't even used a juice i liked with this set up yet so my result might be different when i put bobas in it. still... i find it so odd i get more throat hit from a 3-2, and less th going down to a 2-1

 

[DSmooch]

you should be pretty low with a 3/2 of .8mm, maybe be around .7 , it should fire instantly.... check your contacts maybe. now less th on a 2/1 is odd lol

 

[vapdivrr]

running resistances under 0.5 Ω is iffy imo without batterys that have highest amp draw limits which im sure you know, hopefully your not using just the basic trustfires or something.

 

[peejoe]

here is my ribbon wire setup i call it dragons breath. quadcoil, ribbon kanthal 0.6 x0.07 2/3 wraps, 3mm silica 4 folds, 0.4 ohms ( full charge battery 18490 will last 20 mins or less ) im not suggesting this for daily vaping.

 

[Rader2146]

Anything less then .7Ω with an 18350 is begging for a visit from Murphy and Darwin. If you are less than .5Ω they are probably already en-route.

For the love of God, or whoever you believe in, KNOW YOUR BATTERIES and check your resistance before you even think about touching the fire button.

 

[donneee]

i have a general idea, and i know what amp limitations i have. AW batteries can take a beating, that's all i use. efest are okay but not my preferred. my actual ohm rating won't go on my multimeater cause it's not reading it right? i guess it's too low lol.


ji'm still guessing it's less then .5 since with my 3-2 wrap i had a .8-.7 ohm. i guess i have to spend money on a good multimeter.

 

[vapdivrr]

what kind of multimeter do you have? it should read resistance all the way.

 

[donneee]

i have a gbinstruments t-11. i think i just need new leads cause it's kind of corroded so i can't get an accurate reading. i did buy it from a pawn shop lol. it reads my batteries right though.

Most 18350s generally aren't capable of safely putting out the amperage needed to run a coil much less than 1.0 ohms. Really high amperage rated 18350s (e.g. MNKEs) can only do about 0.8 ohms safely. If you're running a 0.4 ohm coil, then at 4.2 volts you're pulling 10.5 amps. That is really dangerous to do with anything less than a battery rated at 20 amps. If you're coil is at 0.3 ohms, you're pulling 14 amps at 4.2 volts. The only safe advice I can give you is to recoil your wick at a safer resistance level. As you are, you are risking your mod blowing up in your face.

Edit: Looking at my post, it was not harsh enough to convey the danger you are putting yourself into. An 18350, no matter the manufacturer is not capable of the amp draws that you are demanding of it. Vaping like you have described is pure idiocy. Stop it! For myself and the rest of the vaping world, please don't make yourself an example of what not to do! We don't need BT/BP pointing to our vaping devices as potential safety hazards due to malfunctioning batteries.

 

[DSmooch]

I agree.
I've never come across 18350 MNKEs... do you know where they sell them?

 

[Sero]

I see more and more people these days running sub ohm coils on 18350s....it is a disaster waiting to happen. DO NOT RUN 18350s UNDER 1.0 ohm on a mech mod!

 

[jasl90]

I'm not advocating coils in the stupid low range... But in terms of safety, I've never heard of an IMR battery dying violently. I accidentally created a dead short once and the battery got extremely hot very fast but no kablooey... Not to say it can't happen or hasn't happened, especially if you have a defective battery... I've just never heard of it actually happening.

I'd say the real risk of exceeding an IMR battery's amp limitation is simply killing the battery itself... Or at least dramatically reducing its life span. Just my 2 cents.

 

[pdib]

Aren't the ratings for maximum continuous discharge? (vs. 30 second pulse?) Not that your pocket knows what a 30 second discharge is the way your thumb does.

 

[pdib]

Say, for example the MNKE 18650, from a reasonable source (although not god's word): max pulse is 60A https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&ved=0CD0QFjAB&url=http%3A%2F%2Fwww.avidvaper.com%2Fmnke-imr18650-3-7v-li-mn-rechargable-battery%2F&ei=_3KpUdaWBKWIiALVtoDQBQ&usg=AFQjCNGObzjBwjADBtB9J_2Q2dwRbyHdUw&sig2=TWlNv_8gLy_YpZdD8XK2RA&bvm=bv.47244034,d.cGE

 

[jasl90]

A good data sheet will provide both... Unfortunately good data sheets on batteries are tough to come by.

The real question (IMO) is, how are they going to die? With a bang or a whimper?

If its a whimper, you're simply out the cost of a replacement. If, on the other hand, they die w a bang... That's something else entirely...
