Help me decide a mech mod please.

If I change the button to magnets would that help the drop or should I just look into brass or copper mods?
Look very carefully at the bottom tube where the vent holes were drilled thru. So far, 3 of the last 3 I've looked at had burr's left in them from the drilling process. Too fix, remove the lock ring and run a small file thru the holes till the burr disappears visually and them check with your pinky from the inside.......It should all be smooth like silk.
I would ultimately just look into a full copper mod, especially since prices are dropping. Or a box mod since mods like the IPV D2 are under 50$ and perform amazingly!
If you like the style of the nemesis, the good copper clone has extremely low voltage drop.
They are pretty cheap now.
You need to understand the math of voltage dividers in a DC circuit. The lower the resistance of your coil, the more pronounced the voltage drop is going to be across your mod.
Let's ignore the battery's internal impedance just for the sake of easier math.
Let's say your mech has a 0.1 ohm resistance from top to bottom. That's a constant, no matter what atty you stick on it. That 0.1 ohm is in series with your coil.
Let's plug in your 1.0 ohm coil on it. The voltage drop across your mod will be 4.2 * (0.1/(0.1+1.0)) = 0.38v.
Now let's put your 0.5 ohm coil on it. Vdrop = 4.2 * (0.1/(0.1+0.5)) = 0.7v.
Now let's take it to 0.3 ohm, closer to where most of us mech-heads live... 4.2 * (0.1/(0.1+0.3)) = 1.05v.
You see where this is going?
The more you sub-ohm, the better job you need to do to keep things clean and conductive. Getting some Ox-Gard will help keep things nice and reliable. I've had several Nemy's, and with all those stacked tubes, this mod benefits greatly from putting Ox-Gard in all those threads... especially around that dreaded rice-pin.

Thanks!
So what I'm understanding is actually a .7 voltage drop is more than likely just the battery load from a .5 ohm dual coil and I'm not wasting volts due to poor conduction.
Ok well I'm gonna get a copper nemesis and see if that helps any. I'm just wondering by the sum of both do you mean the battery load from a .5 ohm AND poor conduction or is most of it from the load of .5 ohm coils?
If it helps any I tried a 1 ohm coil and only had a .2 voltage drop. Is it just battery load or am I missing something.
Sorry, I mean the internal voltage drop of your battery, which you can't do anything about except to use quality batteries, and the voltage drop across your mod, which you can do something about by keeping it clean.
Copper is great when you keep it clean, but high-current across bare metal contacts will oxidize faster with copper. I'll say the words "Ox-Gard" one last time. You'll just have to experience for yourself the frustration of a quickly degrading vape without it.

I will get some ox-gard lol. Just doesn't seem like grease would help with voltage drop but I have been wrong many times.
Is it ok to put the oxgard on firing button and top cap pin?
Here is a volt test on my kingpin
No load
Under load
At .24 ohm testing agen when my Silver contacts come in

Cleaned contacts on the nemesis and now I'm getting a .35 voltage drop on a .3 ohm coil!!
Amazing!!!
Amazing!!!
Nice.
It's very important to keep contacts and threads clean.
I clean the mod I'm using every day or two.
I use ketchup or Taco Bell hot sauce for my copper and brass contacts.
Adam I have a copper Nemesis myself and it's the hardest hitting mech I own. (Pegasus is a close second.) But be gentle with it. The lock ring threading on the Nemesis is very fine, and I imagine it would be easy to inadvertently death grip it and ruin it since copper is so soft.
I use my SS Nemesis is a banger, but when I'm using my copper one, I'm lounging at home and babying it. I won't even take it into non-carpeted rooms LOL.

Lmfao! Hot sauce! That's awesome. I am not buying the whole oxgard idea tbh I'm getting a .3 drop on a .3 ohm dual coil so that's good enough for me. I also use a SS nemesis and it hits hard. I might grab a copper one just for the hit factor
. Lol hot sauce
