copper tape and conductivity question

[erichpatterson]

i have an abundance of copper tape, and heard the voltage drop can be reduced by running a strip down the inside.

I'm wondering if someone can explain how the conductivity of the mech mod is improved by the tape?
I would like to know why the mod even matters to the flow of current. I have very basic knowledge about electricity and would love to learn all there is.

power from the battery to the atomizer=vapor right?
so is the mod more than a thing to hold the battery? does electricity flow through it? if so,how and why?

i have 2 mechs.a shenxi blackhawk clone and a ?brass?, gold colored tesla m2. i dont know if the m2 is a clone. i dont subohm either but do know about batery safety. the lowest ive gone is 1 ohm.

links to info or an explanation would be awesome!

love the forum, thanks for being here

Welcome to ECF!

You're right...current goes from the battery to the coil. But it has to flow back to the battery to complete the circuit. It does this by flowing through the outside of the 510 connector and through the body of the mod back to the battery.

Mods are pretty thick, a lot of metal. And that tape is very thin. Even though the copper has very high conductivity the effect it has on overall resistance of this "return trip" for the current is, in my opinion, open to debate. And the adhesive holding the tape on has much higher resistance than the copper. The current has to flow through this tape twice in order to take advantage of the copper's lower resistance. That takes away a lot from what the copper offers. Unless they have the tape under the 510 connector before tightening it down.

It's a very interesting idea but I'm not convinced it makes a difference in actual use. Just my personal thoughts.....
Would love to see someone's test results!

thanks for your reply.

so i can assume there is less voltage drop if i use my blackhawk in 18350 mode?

Probably. The shorter the path, and the fewer the number of connections between the battery positive and negative, the better. The difference might be noticable or it might be practically unmeasurable...all depends on the setup.

this is off topic, but could i rebuild my nautilus coil with a premade 1 ohm coil? i dont have any wire, but would like to try if it can be done. it would be economical for me if i could. i'm not in a good spot financially. i dont like the 1.8 ohm on my blackhawk.

Just keep your switch and threads clean. Gotta be better than adding anything inside a tube. Besides I'd be more concerned that the metal tape would wear through the batteries protective wrap and short the whole thing out.

I don't know, sorry. This is a good question to post on its own thread so everyone can see it.

I really wouldnt worry about a .2 volt drop in a mech cuz eventually the battery will drop on its own and you will be in the same place volt wise even tho you went thru all the trouble to do the tape thing... if volt drop values are driving you nuts, make your coil a few tenths of an ohm lower to make up for the drop to maintain your watts...

simple... just remove a few turns of the existing coil... 2 maybe 3 should do it...
