Why does my battery get hot?

[robv1978]

I have a carvela clone using a dual coil .4 ohm rda with an IMR 30 watt 18650 battery.

IMR 30 amp battery? Where did you buy the battery? Do you know who made it?

^^ This ^^

0.4 Ohms @ max voltage of 4.2V is only 10.5A (and 44W).... That should not make a true-30A battery "hot"... "warm", yes, especially if chain-vaping... but not hot.

I had the same problem once.

After very careful inspection,

It was discovered that "I" had put the battery in back words, :?(

Close call I guess, LOL.

Is the actual battery just getting hot is the mod itself getting hot?

Sometimes little metal shavings get scraped into the button and can cause heat issues.

Clean the mod with tarn x and see if that helps. If it is just the battery, I don't really know what would cause that.

I have the same questions lol.

[robv1978]

Yeah I meant 30 amp... LOL Efest 30 amp IMR18650NP 1600mah and a Vamped 40 amp 2000mah. The battery doesn't get hot just a little warm from transference. The button gets warmer than the body though.

As far as metal shavings or gunk my heavily used mlds are cleaned weekly or more often.

[Vaporsmith]

Probably the spring, my nemmy did this to me once. >_>

Why would the spring cause it?

[Vaporsmith]

I've asked the same question, no real response. All I know is, I changed mine out and its fine now.

You would think that someone who is so responsible and so quick to blame everyone else would do more research on his batteries and not expect someone else to tell him everything he believes. Not singling anyone out, just speaking in general. It gets hot because a battery has internal resistance which causes it to produce heat when discharging high amperage.

Use a vtc4 or 5

Both of the batteries mentioned are not true 30/40 amp batteries and fall very short of their maH rating as well. If you are running anything below .6 on an Efest it WILL get warm, period. They are dollar store batteries.

Simple fact is, if you have heat, you have resistance. So whatever is getting hot, figure out why there is resistance there and remove it.

That was what I thought, he insisted they were 30s.

[Vaporsmith]

And I use Sonys so I never have to worry about it.

[Richstag]

Exactly. Say you have a copper contact that is corroded over... that causes resistance...resistance causes heat. This will transfer quickly into the battery, or could just be making the mech feel hot.

Loose contacts do the same thing. They cause resistance and can even cause arching.

SOrry if this isn't explained perfect

[robv1978]

I guess it was the spring or pin. I bought a nemesis clone today and have no hot battery issues. Just the transference onto the body. I'm currently running a .2 ohm RDA. I think my next purchase will be an RDA with heat sinks. There's a few out there priced well.

Hey just baught a joytech ultex t80 cubis max. And put my 18650 battery in it and hit it twice, the mod and battery got hot and idk why? I just got it any tips?
