Is This OK?..4 ohm Build.

[Heavyrocker]

I did a dual coil build on the Kraken with SS cable with a meash sleeve and it came out at 4 ohms,its on my Nemmy and it fires great with no hot spots,it tastes excellent but im a wee but concerned if its too low,ive been using RBAs now for a year at 6 to 7 ohms,any thoughts anyone?

.8 ohms seems a little low for an ss or cable build compared to your original 1.4

As long as you have good batteries in 18650 mode your probably fine

I just dont trust ss that low compared to cotton and chances of shorts occurring...

The build is .4 ohms,2 wicks.

Yes i know

1.5 is my sweet spot on a single with ss but i tend to build higher ohms for dual to come at about 1.2 ohm with genesis.. Just my opinion... .4 ohms with metal on metal concerns me.. Thats all

 

[Heavyrocker]

I think ill be ok,its a shame too break it down,the taste and vapour is spot on.

 

[Royaldrunker]

Ohh for sure.. I had first hand experience on s kraken build ss dual at .7 and taking that damn cap off must have hit the coil cause the battery and button heated up instantly

 

[Royaldrunker]

If ya do 14 wraps of 28 kanthal dual will net you around 1 ohm
Very safe and nice vape

Theres a kraken build thread as well

It depends on what battery you are using. If you're using a 20 to 30 amp battery you should be fine. Otherwise that's awfully low

It very much depends on the battery you're using.

Edit: Doh! Beaten to it.

 

[Royaldrunker]

Yes battery is most important i use sony 30 amps but they wont protect you on a bad short like i experienced.. Instant hot... . 4 ohms with ss doesnt leave much room there..

 

[TrentTC]

The ohms of the coil don't matter if you have a hard short. Whether your coil is .4 ohms or 4 ohms if you have a short it will act the exact same way.

The batt is just a 18650 10 amp panasonic,i think i may break it apart,better safe than sorry,thanks for the help.

Than why are peeps so concerned about sub ohm.. The initial draw on our batteries at that lvl is huge, than
throwing a short into the mix..

Dont get me wrong i build at that lvl at times but its with cotton not ss


Any way he asked opinions on whether it is safe, it is with the best batteries but i wouldnt go that low on that build..,

People are concerned about super low ohms because the difference between .3 and .4 is very large in terms of amperage. Amperage doubles between .1 and .2 ohms. A .2 ohm coil pulls about 20 amps. A .1 ohm coil pulls 41 amps. So if you build a coil at .2 ohms and your resistance drops at all you are really getting into danger. A .4 ohm coil with a freshly charged battery pulls 10.5 amps. That's already over the limit for a 10 amp battery. If that coil were to drop to .3 in resistance all of a sudden you're pulling 14 amps and are definitely in danger. Hope that helps.

A hard short is danger no matter what. Your coil resistance goes out the window. Your battery will get hot and is in danger no matter what your intended resistance was.

Thank you than were on the same page.. Ss isnt as forgiving as cotton or silica wicks..

The original question was based on build not battery.. I thought it was too low.. Thats all.. Definitely with 10a batteries.

I just pulled the other wick out,now vaping at .8 ohms,not takn any chances,single wick for a single guy.BTW,i didnt plan that .4 ohm build,ust worked out that way at 3 wraps each on the rope.

 

[TrentTC]

Probably was the right thing to do. If you really enjoyed that .4 ohm build get some MNKE or SonyVTC batteries

Actually it the .4 build tastes better than the .8....massive clouds too.

I would say if you want to make .4 ohms a regular thing then definitely you need to upgrade your battery to at least the AW 18650 1600mah if not the Sony or MNKE beasts. If it's just going to be this once you can get away with a slightly under-rated battery. Our batteries have 2 ratings . .a C rating and a Burst rating which is much higher. For safety, I always buy and use batteries with appropriate C rating for my application . .but I definitely have exceeded the C rating for short periods of time with no issues.

In my opinion it's common sense. If your mod, battery or button get more than just slightly warm . . .stop. For those of us with butter fingers and lots of coils under our belt . .the idea of pushing the fire button and blowing your head off is silly. If that were the case, I'd be the headless horseman, lol.

One thing tho is if you do happen to exceed your battery in the short term . .you want to make really, really, extra double sure that your mod doesn't fire by accident for an extended time. .ie . in a pocket or bookbag, etc. That could be a really bad scenario.
