What am I doing wrong? Keep experiencing battery hot spots.

[totalnewb]

Hey,

It's been about 3 months now that I've began rebuilding on my own, and I experienced one issue with new builds. While I've made some clean builds, the bad ones I out number the good. Not sure why, and how to go about fixing them. Anytime I take a pull of my mod, longer than 5 seconds, I get a hot spot on my mod/battery. The problem happens when I take continuous pulls. Has anyone experienced this problem... and if so, how were you able fix the problem. Obviously I'm doing something wrong but can't figure it out.

I'm building on:

- Tobh Atomizer
- Turtle Ship v2 by hcigar
- A1 Kanthal 24g
- 100% Organic Cotton
- Sony 18650 2600mah VCT5

Many thanks for reading.

How many wraps are you making? Coil I.D.? Single coil or dual? What is the resistance of your build?

 

[Topwater Elvis]

What is the resistance of the coils you're building?

 

[totalnewb]

I'm doing 7/8 wraps, and reading about .3 ohms,

 

[Kaezziel]

.3 is a bit low for me, but the VTC5 should be able to handle that with no problems... which part of your mod is getting hot?

 

[totalnewb]

The hot spot happens near the bottom, close to the negative side of the battery.

 

[Kaezziel]

That's odd... wonder if it is similar to the problem this guy is having?

Maybe try cleaning the threads and contacts on your mod also...

 

[totalnewb]

I have. I actually spent a good amount of time cleaning my entire mod, atomizer, battery contact points, the trigger and even the screws for the atty. And still have the problem.

Give this thread a read-through...

I'm trying to do a search similar to your issue as I have no good answer for you... or perhaps someone else can pop in with a better suggestion...

a. The term hot spot refers to a part of a coil that heats up faster or hotter than the rest of the coil. A hot battery is just a hot battery..

b. Is your battery getting hot? or is it just the mod?

c. What are you reading your resistance on? If it's not as accurate as you expect it could be closer to .2 which is above the continuous rating of the vtc5.. From what I've read you might get warm at that point, but it shouldn't make things hot. It could be possible that the threads on your clone aren't perfect, any burrs or small spaces could cause arcs that would create heat.


It could be something not making correct contact somewhere.. it could be a thread that has something in it.. etc at that resistance little things can make a big difference.

k702 and Kaezziel, thanks for the info. I'll check my build and mod, and see what happens.

 

[Kaezziel]

Good luck, totalnewb! If it doesn't sort out, just come back and post what you've tried again and let's see if we can help you work it out...

 

[totalnewb]

Thanks for the info.

k702 and Kaezziel, thanks for the info. I'll check my build and mod, and see what happens.

you never answered whether the battery was getting hot or just the mod?

I had a similar issue with my hcigar turtleship V2 and awt 35a batteries, what I noticed was there was a small tear in the battery shrink wrap towards the top and it was making contact with the side tube causing a hot spot. I covered that area of the battery with some tape and haven't had that issue since

Hi totalnewb! I don't have anything to add to the discussion since I'm not into rebuilding just quite yet...just curious, what will you do about your username when you aren't a total newb anymore? I see it now, totalnewb... Posts: 8,107. Lol. Welcome to ecf! Good luck with your hot spot and stay safe!
