Ohm's Law: Safe Sub-Ohm Twisted 26g Quad Coil

[Mechanical Andrew]

Using the pen twisting wire technique to twist two 26g kanthal wires together, and build a quad coil out of the twisted wire. Here are a few pictures of the build in progress.



Build came in at .12 Ω. With the Vappower IMR26650 4200mAh's full charge at 4.2V.
Apply some ohm's law to that.


4.2V/0.12ΩxI
I=35Amps

My batter is rated for 60 Amp pulses and a 40 Amp continuous discharge.
35Amps < 40Amps.
This build is safe.
There is no volt drop on my mod. Volts register at 4.23V @ the 510 contacts for the atomizer.

Here is an animated gif of me blowing a cloud with this build: Cloud

A few things:

you seem confused as to whether it's 0.12Ω or 1.2Ω

What battery is rated for 40A continuous? I'd like to get one. We can disregard pulse ratings as totally meaningless because they vary from manufacturer and are marketing nonsense.

Nice Ohms law diagram.

The build may or may not be safe depending on your battery, but in any case you are thrashing your battery to within an inch of its life!

Your build looks good - you just maybe 5 years ahead of current battery technology to safely power it, but aren't we all?

Sorry about that. My math is right, but it's .12 ohms. Post should be updated now.

Looks right. A little extreme, but nice build!

Pulse ratings are not marketing techniques.

I'm calling shenanigans on the 0 voltage drop. You're not measuring under load or something. It's impossible to not have a voltage drop, and it goes up exponentially the more you stress your battery.
