Reo Grand Voltage?

[hildicat]

Been using my new Reomizer on my old Reo Grand. Since I expect the Grand to run at about 3.7V I made a coil at about 1.6Ω, but it felt very anemic, hardly any heat or vapor. Kept lowering the resistance of my coils and finally found a satisfying vape on a coil of 0.8Ω.

Crazy, right! I kept thinking, 'how can this make any sense?' On my VVs I usually run about 2.0Ω at 4.2V. The math just didn't seem right for the Grand.

Then I remembered I have one of those in-line volt meters. Slapped it on the Grand and it read my battery at just over 4V. Then I put the Reomizer on top of the whole thing and fired. Its telling me that under load I am only getting 3.4 volts to the atty.

Its been a while since I used a standard Grand, but I don't remember having that much voltage drop off under load.

Does Old Grand need to in for a treatment?

you might try giving it a cleaning like the firing pin and other connections

Try a standard atomizer and let me no what the voltage drop is .
On a 1.5 ohm atomizer the voltage drops to around 3.8 volts with a fresh aw imr 18650 charged to 4.2 volts any lower then 3.7 and there is something wrong lose connection dirty mod hard to tell from here . Keep me informed

Well, believe it or not, I don't have any 'regular' attys anymore. Ditched them all last month in favor of rebuildables. Probably should have kept a few around but I was cleaning up my stash and never thought I would need one again.

BTW- the Grand is all cleaned up and freshly Noaluxed. Last time I used him was several months ago, back when I was playing with a drilled out Phoenix. I collapsed a spring back then, but it has since been replaced. Could a short have damaged something else?

i have 3 ERAs and 2 reomizers and use them on grands with aw imr batts a 1.5 ohm coil should rock your socks off. there has to be another problem because i can get easily 3 to 4 mill of juice on 1 battery

A 0.8Ω coil would be hell on a battery, and is more than likely what's running it down under load.... Are you using AW IMR's? How old is your battery? Try wrapping a 2 - 2.5Ω coil, and check your battery voltage under load. If your spring collasped, there is not much else that could have happened (mechanical mod) to cause your issue.

Put the mod is a padded envelope you can ship it to me for $1.60 . I will go through the mod and make sure its running properly

Got it. Will try to get him out today. Thanks Rob.

You do realize that with a 0.8Ω coil @ 4v, you are attempting to pull around 5 amps (20 watts) from your battery.... I can almost guarantee there is nothing wrong with your mod.. (Especially if it's firing a 0.8Ω coil)

Not to go too off topic but I go .8 and .9 ohms all the time on my genesis devices and the AW IMR batts seem to handle it pretty well. The 18350 struggle I think the but the 18650 rock it out and come back for more.

Back on topic though I have found the REOmizer (and chalice) pretty anemic as well on the non VV REOs no matter what coil I make .... I have no logic to explain it. A couple days ago I wrapped one with 30 gauge that came out to 1.4 and I put it on the VV but had to crank it down to 3.8. I thought this would be a perfect one for the non VV woodvil but It just didn't perform well for me.

Both my REOmizers (unlike my chalice) seem to take a primer puff to heat up though I make the coils the very same way ??
Both REOmizers also can pop on my like a sun of a gun where the chalice is almost silent. Not sure what the difference could be?

That is odd Tim I don't get any popping you speak off . When I run a rba on a 3.7 volt mod I use 28 gauge wire and its a vaping monster

@hildicat - is the air hole intake on the same side as your coil? Make sure you place the coil on the same side as the air intake. The closer the better. Just be sure not to let the coil touch the atomizer housing.

I am also getting popping with my reomizer. 32 kanthal w/ cotton gauze.

Maybe that is the difference I use silica wick . I have never experienced it with the atomizer
