Actually the smaller wire would have greater resistance than the larger wire so the larger wire would be longer to create the same amount of resistance giving it even more mass than just it's diameter.

Yea I guess your right....stupid fat electrons...if they would diet they could get thru that thin wire easier!

I do not know what is available now-a-days, but back in the 1920's, rheostats had wire with different formulas. So it was possible for two wires with different lengths to have about the same resistance. Or whatever. You guys are getting me all fused up right now.

The types of alloys the wire is made out of will make a difference in how well it passes electrons also. Typically though a rheostat will use a single carbon strip that varies resistance from one end to another. Early jetronics fuel injection systems used this type of rheostat for the mass air flow sensors.

In the 1920's they did not know how to make a carbon resistor. When they finally learned how, they also began making potentiometers with carbon. Some of them had a taper to vary the rate.

I have been lurking here for a couple of days now to hear about the r4.

I am going to try to get this correct.

So far it seems that badkolo only has the 808 XL r4 and has tried it out on his 510 thread battery (with adapter) and so far it's doing great?

Am I also getting it right when I hear the 510's that have come in are actually r3.75 or so? lol! Are those the xls?

Does anyone know if the the 510 XLs are expected to run at about 3ohm?

This curious mind would like to know!

Thanks in advance for any clarity I can receive in regard to this! :)

I see that's true...The 1920's would have been a difficult time for electronics. So what was it really like? The incites of someone who was actually there would be fascinating to say the least.

That was back in the Bronze age and you guys had to hammer out your own wire isnt it? LOL

Aw, come on now. Do you really expect to get clarity from from this thread? I'm hoping for a 510 XL at 3 ohms too, but haven't actually seen one yet.

Guess I received the Frankenstein as well... Mine does not Have the sleeve around the "main" part if the cup I have yet to disect it and see whats really inside.. I will do this tonight. But for argument purposes I left my e2 standing upside down all night long with only the silicone filler ring inside... And I had no leak at all!!

EDIT--- apparently I did receieve r4's from vaping.com prob explains why they don't leak.. Vapor is amazing but looks like there is some hot glue around the bottom

HAHAHAHA!!!! Bus bars are awesome! I think some vehicle manufacturers need to go back to a bus bar design for isolating grounds.

The old days: When in doubt about a ground- Weld, clamp, or bolt two pieces of massive metal together, allow it to oxidize for 60 years, and note that the ground is still good.

The new days: When in doubt about a ground, make multiple contact traces on a circuit board, everywhere, on multiple levels, in a manner that cannot be traced, use the circuit for 60 days- and replace.

Cavemen for the win!

i have 510 3.0 ohm xl right here, it says hi, the new ones if ordered at 3.0to 3.2 SHOULD arrive in that range.


Br is so old he knew burger king when he was a prince.

Br is so old he was around when central park was just a plant.


sorry br, i had to.

Waiving hi wistfully at your 510 xl! I look forward to your trying it out and then maybe I'll find out if the elusive Unicorn is real! I look forward to your review. :)

As to br, being so old?

I can't cast any stones that way. I'm so old that I just gave up smoking after 43 years, but I do remember Central Park being completely treed (much history there). As to the Burger King, I don't think he was even a glint in the eye of his father the previous king and his mother, the queen, and my first trysts with fast food was with White Castle...hmmmmm...maybe that's where Burger King's Dad and Mom got their "inspiration"? ;)
