would anyone happen to know the nemesis clones voltagedrop and how to minimize it as well?

ive been hearing about that lately. i know i probably sound dumb for asking but where do i apply the tape as well as what should i avoid it coming in contact with?

voltage drop is not a fixed value for a particular piece of metal; and by definition, clones are not going to be very consistent from one to another.
furthermore since you mention the popular nemesis, that varies to much because you have copper, brass, steel and mixed versions of clone nemesis, as well as multiple configs of the nemesis.
To minimize voltagedrop- I guess you'd pick the copper nemesis.
(personally I'd pick the steel)
i have the stainless steel version. i tested the voltage drop with a multimeter and it was around .5 i believe. stainless does absorb heat for crap either lol
You tested with a multimeter - okay with what ohm load?
V-drop, on any mod, can increase dramatically as load increases. This is a common occurrence.
Also - What Battery are you testing with?

The voltage dropped
- from 4.2 battery
- to 3.7 under load ?
Using a 0.3 ohm coil :
3.7 = I x 0.3
I = 12.3 amps.
0.5 = 12.3 x R
R = 0.04 ohm
You mod+batt total ohms is 0.04 ohms

about .3 ohms. for some reason the ohm reader on the multi meter would not work. it gave everything a .1 reading. its an analog. and i was testing it with a efest 18650 35 amp
Stop and get a digital meter for testing - a good one.
You will never know what is going on with an analogue meter.
i.e. .3ohms or .39ohms
If you properly cleaned all your contacts and threading - don't forget the 510 on the Topper, as well as coil connections, you are likely chasing ghost. Should chase the clouds instead and enjoy.
Remember, the top pin has 2 contact sides - Battery/topper
I have 9 different Nemesis - minimal drops and near identical performance - if one does get weak I break it down and clean everything up. Good to go again.
voltage = current x resistance.
battery voltage = voltage accross coil + voltage drop
I updated the figures for the 0.3 ohm coil
your mod is 0.04 ohm
battery voltage = voltage accross coil + voltage drop

Get the fatdaddy nemi upgrade kit. It on my next to buy list but seem like a good investment for the clone.

There sure is a lot of confusion about voltage drop. What most people call voltage drop is actually battery sag.
In order to measure voltage drop properly 3 calibrated meters would be required and connected as shown here.
The meters with the 510 connectors will tell you the voltage at the atomizer but they can't take into account how much the battery voltage drops under load so they can't be used to measure voltage drop.
In the example a fully charged battery under load could sag down to 3.81 volts and the voltage across the atomizer is 3.80 volts and the voltage drop across the MOD would be .001 volts which is higher than I would expect to see given the resistance of the worst case metals is something like 6.4 X 10 to the negative 7 ohms per cubic meter.

I'm not sure but be careful with the Nemesis. The one I tried using stopped working around the firing button and fell apart and there were so many little parts, I lost the pin and just gave up on it.
It vaped great though, I love them, just remember to be careful when taking them apart. And I'd suggest getting a magnet switch to replace the double spring that's crunchy.

I have the same mod. With a new Sony VTC battery fully charged I get around 0.4 volts drop at 0.5 ohms. I would say yours is doing about the same considering you're using 0.3 ohms.
I don't worry too much about voltage drop from the mod. The battery has much more influence on your vape than the mod does, unless the mod is really bad which these aren't. I clean all contact surfaces on mine about every three weeks with alcohol and a paper towel or Q-tips. I used to use a bit of Noalox on the threads but I found it didn't help extend the time between cleanings. I find it's important to take the switch apart and clean all those parts as well.
As your batteries age they will have more voltage drop under load. It can get quite significant. My first pair of batteries got up to almost 1 volt at 0.5 ohms before I retired them.
I never realized the Nemesis mods do this, is there anyone that happens to make good copper contact pins for these guys? That, and what is the best line on the magswitch kit?
You misread the subject of the thread.
The Nemesis clone mods do not have some special voltage drop problem.
You gave an example but
1: you have not said what is the voltage drop in your example
2: neither have you said what is the battery sag in your example
