Button's getting hot?

[HereticElven]

Hello,

Last night I rebuilt my Stillare to a .14 parallel dual coil with 26g wire. After a few clouds I noticed the button getting warm. I'm hesititent to use until I know why/what is causing this. I've put it on my ohm meter various times and each time reads .14 so don't think its a short with the build.

Set up is as follows:
Coil: Dual parallel micro coils 26g reading at 0.14 ohm
Atty: Stillare(clone)
mod: Sentinel M(clone)
Battery: Sony VTC5(full charge)

I've never experienced this with any other build(Even builds at the same ohm) and am worried that I may cause some damage to my battery or mod.

0.14 ohm at 4v is 28+ amps and over 110watt. I'm not amazed your gear is running hot.
Are you vaping or splitting atoms?

I'm well aware of the wattage/amps being pulled. I had originally thought that I may have exceeded the amp limit of my batteries. I've had builds in the past around .13-.15 that never caused my button to get hot. And just to clarify when I say it got hot I mean it got warm enough that I could feel it. Top was hot(obviously), middle of mod was cool and the button was getting warm. Pulled the battery out and was cool(ish) to the touch. Just want to make sure it won't escalate to a bigger issue if I continue to use this build.

(Also I apologize if any of this comes off rude. Just been a rough day and don't want to lose any more mods today DX)

You are running your battery at close to max, and I'm positive you are exceeding the rating on you switch. Not a lot out there that can handle that kind of load. Be careful, .14 ohms is getting dangerously close to a short.

 

[HereticElven]

I didn't realize that my sentinel's switch would have a max rating on it. Any idea what that would be?

(Never heard anyone saying anything about that with most tube mods)

 

[Josh Bray]

I don't know about the rating on the switch but I'm willing to bet that if you look at your contacts and the bottom of your battery there will be little black marks, most likely caused by the arching

 

[pwheeler]

You're right. You have a fully mechanical mag switch. I still imagine it's warming up from the large power drain.

 

[HereticElven]

Is that a problem though? Will that cause damage to my mod and/or battery with extended use?

It could cause a failure of the battery cell..

I hope you checked that resistance on a couple/few different ohmmeters so you know it's .14 and not .1 or lower.. Once you get down into that range of resistance, Amps and Watts go crazy and increase by quite a lot very quickly. Really have to say, if you care about safety at all the setup you described is not advisable.

I've checked on my meter and my Tesla. Also checked it on two at my local shop. All are showing .14 so its within acceptable range for the battery. Was just told that its the spring starting to fail in the button and that I should upgrade to magnets when I can.

Magnets will fail when heated too.

The switch itself isn't up to the task you are asking of it.

Same thing happens on any part of a mod that is conducting lots of electricity and has little direct metal to metal contact area. The heat is coming from the arc, plain and simple.

Get a better mod to cure the issue, you can't add metal to metal contact.

This is where very close fitting parts outshine loose fitting ones. Heck my out and about throwaway hcigar clone nemesis that is fairly nice can't carry the current of a 0.28 ohm coil where the tube sections join. That's simply due to bad threading. The switch too has a wide margin of tollarance and gets hot at that range as well.

Building higher ohm coils is an instant fix, otherwise you are seeing your mods limits.

Thinking about upgrading as it is. Been looking at a copper AR as well as a few others that my friends have been recommending. And this isn't an all day setup either. More of a show piece when my friends start asking me about lower ohm'd builds. Just was concerned.

Anyway, Thanks for all the info/input.

Actually, unless the magnets make contact with each other and create a better circuit path then the spring, the magnets may make the condition worse. Reason a hot button 9 times out of 10 is poor conductivity from the button to the body of the mod. Magnets only make this worse because the button now floats more with worse conductivity. If the magnets touch when it's depressed and making contact with the battery, they they will help improve the issue. Most likely this is really hard to achieve simultaneous contact of two surfaces.

My preferred method of how to fix this issue (and I done it to a couple of my Atomo mods that are known for this problem) is a nice heavy Nemesis spring, Then I cut and shape it to the desired shape and weight of the throw. I usually keep the weight of the throw a little heavier then normal to help prevent accidental firing.
