Thats great, but the main reason for the low drop at that low resistance is that there are 3 batteries. The majority of voltage drop (much more than the mod), is battery sag under load. With three batteries, each battery sees 1/3 of the load. You would probably get the same drop with a single battery and a .45ohm resistance.

I'm glad I saw this!!
I am going from a fresh battery at 4.2v and I thought I would see what voltage drop I was getting.
So I put my dual coil .5 ohm on a nemesis and tyred it.
It went from 4.2 to 3.7v and that is optimal performance for 1 battery and a clean mod right?
Seeing that the OP had a .20 drop on 3 battery with basically the same build I have then I just multiplied the drop times 3 and yippy it is .60.
Yes I said yippy...lol

The drop increases as the resistance decreases. This is due to the battery seeing greater load. OP is running a much lower build, so higher drop would normally be expected. But this is mitigated as the load per battery is lessened. As I said, much of it depends on your batteries, but some mechs will get better results, usually when clean and made of copper. VD is kind of irrelevant unless you are comparing different mods with the same build in the same atomizer and with the same batteries. Then you can directly compare which one puts out more power with all other variables the same.

Nailed it.
