Some may have already seen this, but looks like we have our first zero voltage drop mod!!

Hmm...There is a LOT of info missing from this. What's the source of this info? How were the test done? What's with the 6.90V?

There is no such thing a zero voltage drop when we are talking about battery powered mods. If you leave the battery out of the equation and only account for the voltage drop through the mod, then it is pretty easy to get near zero loss.
 
This is an independent test performed by someone in our Los Angeles Vaping community.
In the Calivapers forum, mechanical mods, mod test setup thread.

He has put together a test setup that eliminated the variables like the battery and the coil.

Here's some shots of the tests he's done. He hasn't tested everything, just those mods he has, people have brought him.

Sorry for the lack of information. Here is the text from the first post in the Calivapers thread.

"So, I had nothing better to do but setup a rig to test some mech mods based on the conversations here.

An Astron power supply as the main power source and connected it to a 1 ohm 100W resistor for one test and 2 1 ohm resistors in parallel for a .5 ohm test. Voltage reading was taken at the mod.

One problem I ran into was the regulator would not output over 6 amps at 3.7 volts into a .5 ohm load. It needed to be at a higher voltage, so I used 7 volts to output 13 amps of current through the mod. This is will come out to a load of about .3 ohms at 3.7 volts.

The testing is to isolate the mod itself and to get actual voltage drop and current flow and not be influenced by atomizer and battery resistance.

Note that firing the device with varied pressure, pushing the button to the side when firing, etc., causes voltage variations. The mod is fired multiple times and the most consistent voltage is recorded."

My take away is that everything tested gets tested with the same setup, while removing the variables. Gives a standard for comparison.
 
No battery. I think that is one of the things I like about what this guy is doing. Eliminating the battery and load lets us compare mods and materials. The theory holds. Copper is a best, Brass is slightly lower, & Stainless is the least performer. The BCV mods tested have the same specs, so it gave a good comparison on material performance.

Honestly, the reason for such a low drop is because of the lack of top pins at the 510 connector. Just a tough mod to get right now.

I want a solid silver mech :D Now that would be interesting.

Additionally, if you remove one of the major components of the system, in this instance the battery, your results are invalid. Who walks around with a test rig hooked up to their PV instead of a battery?

Interesting that the Brass Nemesis is also listed as having no voltage drop. Wonder why that piece of info is buried WAY down in the table?

If I understand what he's doing (and I may not!), I can't see where eliminating the battery (and the coil) from the test bed invalidates the tests ... what the test seems to be measuring is the voltage drop experienced only through the mod material and connections ... obviously, any mod will exhibit varying voltage drops with different batteries driving them, simply because of the internal resistance of the battery. (I think ... :blink:)

Exactly. So using the same battery and atomizer to test every mod would give consistent results. The only purpose of this 'test bed' is to create a false result.
 
@SimianSteam Very valid points. I agree there can't be a pure zero volt drop. There has to be some resistance. He may have to get more accurate equipment.

For not being a valid test, I will respectfully disagree. It's not about how the mod performs in our hands with our batteries and coils. This test shows how devices and materials are performing in their construction. Though I think when we're down at the 0.04v drop and lower I wouldn't know the difference. Some may, I'm not that advanced. The Brass Nemmy has been a good performer. Lots of folks like it!!

Highlighted the WTH statement... Umm, how it performs in our hands with batteries and coils is ALL it's about.

Great question. I doubt nothing tangible. Do you think the charts are good for comparison when shopping for a new mod?

Maybe vaguely. I did find it interesting that the GGTS has such a high drop compared to others. Half a volt is definitely tangible. When you get down to the difference between .03 and .01 or whatever I doubt the difference is even noticeable.

The biggest problem I have is that I would not trust data from a biased source. If this was posted by an uninterested party then maybe I'd give it some credence, but since it was posted by a mod maker... I know, I know, the testing was supposedly done by community members, but you don't know what kind of incentive they got for doing it.
