MOD heating up Randomly

[SgtSponge]

So I have a MX on a Nemesis running with a Lg 3.7v 18650-HE2 2500mah (Amazon.com: LG HE2 18650 2500mAh 35A 3.7v Rechargeable Flat Top Battery: Electronics) and randomly sometimes the mod heats up where I hold it, super hot and then it goes away right away , and its not everytime I fire it. I am very confused is something wrong?

First, I trust that you have removed the battery, while you discover what the issue may be, yes?

 

[Topwater Elvis]

Have you cleaned all the threaded areas lately?
Screws that hold coil legs tight?

What resistance coil are you using?

Yea I removed the battery, it happens right at the threads where the two pieces meet.

Is the contact pin in the bottom switch screwed down properly?

Well, running it at .34 your mod is going to get very hot after just a few hits. I run a .4 and after 6-8 hits, its really time to let it cool down a bit.

The suggestion on the battery should`nt be ignored. Sony`s have been used in this specific application for along time now, the LG, I`m not so sure.

Yea i assumed it would heat up but the MX isnt too hot its were the battery is and sometimes its on the first hit.

The LG HE2 is a perfectly fine 20A battery.

At .37 he is pulling in 11.35A, that gives 43% headroom. I don't see a problem here.

I however don't recommend sourcing batteries from Amazon or Ebay, what you are actually getting is a crapshoot.

That`s good to know. The Sony`s are getting out of this world.

Heat is a warning sign, even using low sub ohm a hot tube, switch or battery should not be considered normal.

Warm is okay, anyone's definition of hot not okay, first sign of something aint right / unsafe condition.

BTW,,, .34 = 12.352a & 51.88w

Should I rebuild a less subohmy build?

Not if you don't want to, just find & fix the cause of the heating problem.

If it's heating up where the 2 pieces meet (don't know which 2 pieces you're talking about) that would seem to be where the problem is.

Are you talking about between the mod and the head, or between 2 sections of the mod, or something else?

The nemesis clones [do not know of yours is authentic or not] seem to have a pretty prevalent problem with that.make sure your rice pin is still in the switch for one, that was a big problem with mine.

OK, I get that. I should have said very warm, or pretty warm. I guess HOT would mean to warm to hold, Too HOT to hold is never good.

Hasn't it been basically confirmed that the Efest 35a 2500mah 18650s are actually rewrapped HE2's?

As already mentioned, the HE2's are 20a but can handle a 70a burst for 60+ seconds supposedly, so the cell should be fine at his resistances.
