So confused. I dont wana die.

So much wire not in contact with cotton, that's gonna be one heck of a dry hit, enjoy.

Ok so how can the newer mods Safely run at 250 or even older mods at 200W (regulated not mech) if most high drain 18650 batts are at 20W continuous discharge? even the bigger mods with 3 batteries should not be able to do this safly. like 20W (continuous discharge) X 3(batteries) = 60W of safe continuous discharge. not 250. So what am i missing here?

I noticed you said 20 watts of CDR.

That's patently false.

Ohms law is amperage = voltage / resistance.

your wattage is your amperage multiplied by your voltage.

I=v/R

20 watts = 20 amps at 1 volt.

20 amps for a single 18650 (4.2 volts) is at .21 ohms for resistance.

Which means the highest CDR for a battery equals 84 watts.

If you have a dual battery, you have to change your voltage. Voltage multiplied by the number of batteries will give you the right amount.

For two batteries, 20 amps is at .42 ohms.

But, at 8.4 volts from the two batteries, you're pushing 168 watts at 20 amps.

same goes for three batteries. At 12.4 volts, you'll be running 252 watts at 20 amps.

That's how ohms law works.

edit: In normal circumstances, you will run 20 watts at 4.2 volts and 4.7 amps. Which is well below the CDR of the battery. (cdr is continuous discharge rate)

a bit off topic but how dumb is it to be vaping this build i made on an old lipo that gets discharged wayyy too fast?. also in escribe, how do i know if its actually damaged? this build is 0.03 ohm
View attachment 722443 View attachment 722445 or just dieng?

Where did you get this, or can you tell me how you did it.

I have some old wire laying around and have a fence in the back 40 needs mending...

Are dual battery mods series or parallel normally?

 

[Kiyle the Manlet]

Are dual battery mods series or parallel normally?

Usually they are wired in series, but not always. Hopefully these diagrams help.

 

[untar]

They are normally what the battery orientation indicators suggest, nothing else really matters.

Most of the mods you buy will be in series but don't take it for granted, there's at least one thread here with an accident likely caused by a guy putting batteries in series orientation into a parallel mech mod.
There's also mixed (series and parallel) or convertible (series or parallel) on the market, and nobody can tell what the new shiny thing will be tomorrow so keep your eyes open.

Correct. However, it isn't necessarily the case that the battery indicator will be the way it is wired.

The VCM stack is a good example of that. Flashlights, too. Those are in series. However, I can imagine a wiring scheme that makes a parallel look like a series.

My point is that you should do your reading about a mod before buying it.

ESPECIALLY Mechs.

Hard to confuse a single cell...

For sure, but ohms law is still important to know

 

[Zutankhamun]

I know my friend but if your getting fooled by division then I’m sure battery orientation will trip you up.

Well that's why people ask questions. I've built box mods before, and I've sold mechanical box mods before. I've never had someone hurt themselves with the information I give them, and I don't like seeing people get hurt because of a lack of information.

 

[Zutankhamun]

Agreed. I think it is vital that you understand a cell and the physics surrounding that cell before you begin flipping and arranging multiple cells.

I think you should be comfortable with one and then the other.
I don’t think stacking is a good idea but you’d hope that the person involved understands how a singular battery behaves before embarking on multiple cells

Well absolutely. I agree that no one should use a sub-ohm multi-battery device, let alone a mech, unless they understand the battery.

Also, stacking the battery is a parallel set up. I hate the VCM stack, but it's not the most dangerous mech I've used. (noisy cricket)

Stacking is a SERIES set up....no?

 

[Kiyle the Manlet]

Yeah, you're right. Oops.

I wasn't really thinking too much when I typed that.

 

[the wind]

Stacking is a SERIES set up....no?

if you have two in series if 4volts would make it 8volts.in parallel 2 would still only be 4volts.so yes to me stacking would be series.

Series is when you wire + -+ - by stacking it does the same as wiring it. If you double volts you're going to draw half the amps for same watts so I guess it make sense for mods to be wired in series

Try putting 3 amp batteries in your regulated mod and firing it at 150 watts.

Then tell me if you still agree with that statement.
