My battery gets warm when I pulse

[Xanarkhan]

Today I bought my first RDA because buying new coils was getting to expensive for me.
I watched a lot of YouTube Videos about making your own coils, how to change the cotton etc.

Well, I changed the cotton in my dripper just a few mins ago and noticed that my mod (Revenger X) got warm.
Kinda like holding a piece of metal in your hand for a long time.

I noticed it after dripping some liquid in, pulsing the fire-button to let the liquid soak in, pulse it again, drip more liquid onto the coils, pulsing it again.

Do I have to replace my mod or is that totally common?

Its only starting doing this since you started using this RDA?
What were you using before and at what wattage, what wattge are you using this new RDA at?
What batteries are you using?

 

[Xanarkhan]

Yes, it started when I first used the RDA. I run the RDA at 60W. Before that I used a SMOK Baby at 45W (Top Airflow).
Batteries are US1865OVTC5A

Batteries are good.
No significant increase in wattage.
What resistance is the Smok coil, and what coil/s are you running in the RDA?
Does the mod have a metal or plastic casing?

 

[Xanarkhan]

Both at 0.2 Ohm. The case is made out of metal. For the RDA I'm using Clapton coils right now.

Good choice on going to rebuildables.

Maybe this isn't what you meant, but: Regardless of the build, I would never pulse the fire button to let the juice soak in. I'd make sure it's fully saturated before touching the power. Any fibers that are dry when you apply heat will scorch the wick, and it can't recover from that. When juicing a fresh wick on an rta/rda, it doesn't take long to soak in fully, but be patient. It'll only take about a minute, on an open coil/wick.

Are you sure the coil in the rda is .2? Is that what the mod shows, or did you purchase .2 coils?

Like others, I need more info. What RDA is it? Single or dual coil(s)? 0.2 ohms is what the mod shows? Did you even see what the mod shows? Always start lower watts and gradually work your way up. What material is the coil(s)? Kanthal (also called A1) Nichrome (Ni80), Stainless steel (ss316l) or Titanium? The mod feels warm (at the top where the RDA connects)?

The RDA is a wismec guillotine v2 using 2 clapton coils that came with the RDA.
My mod showed 0.2 ohms but it went down to 0.16 Ohm.

My best guess so far is that your RDA is getting much hotter than your tank. This is normal as in a tank the atomizer chamber is surrounded by eliquid which cools and insulates it. This heat is then inducted into your mod, and you mod becomes noticeably hot.
Maybe the 'pulsing' you spoke of is increasing the amount of residual heat in the atomizer, as it may be increasing the actual number of seconds the coils are heated during a given period of time as opposed to the tank.
Having said that, at the wattage levels you are using this seems unlikely to me, but it's the best scenario I can come up with based on the information at hand. Can you retest to eliminate the possibility that what you are experiencing is not just psychosomatic?

 

[Xanarkhan]

Well, the mod I'm using is a good one. The batteries seem to be good ones as well. The RDA seems to be decent and since it's made from Alu, I know it's getting hot and I guess the pulsing puts a tiny bit of stress on the batteries.

Once my vape-shop is open again, I'll ask the guy to take a look at it.
