Mechanical reos will be seeing some upgrades

[Filthy-Beast]

Got mine Friday, rebuilt while camping.

BEFORE:
Cyclone + AFC dual coils reading .37 ohms on the meter.
Sony VTC 5 reading 4.17 at rest
Battery under Load 4.07, Battery voltage drop of .1
Coil reading while firing 3.50, mod only voltage drop of .57

total of mod + battery voltage drop of .67

After:
Coil reading while firing of 3.85,

Mod only voltage drop after SO kit is .22

for a total of battery + mod voltage drop of .32, an improvement of .35 volts

Question here.
Using the same battery, if different loads are place on it, does the internal resistance of the battery remain the same.

 

[Filthy-Beast]

as the amp load increases the v drop will increase as well

 

[ltrainer]

as the amp load increases the v drop will increase as well

and the batteries internal resistance as well?

 

[Filthy-Beast]

No the resistance would stay the same. As you push a higher amp load at the same resistance the v drop increases. With use and age a batteries internal resistance will get higher though.

Just received my HO kits for my mini 2.0 and OG mini installed 1 in the Mini 2.0 and wrapped up a .8 ohm coil and BAM sounds like I'm frying some serious bacon

Vape mail today!!! Got in the rebuild kit for the grand and a few goodies from my super_X brotha... Oh yeah...

I didn't gain a whole lot with the new kit, but its better than what it was. I tested it with a partially drained battery and a fresh one. I am happy with the results overall though. I'm not sure why the voltage drop is higher on a fresh battery as opposed to a used one!! Can anyone explain that? It's not hitting a whole lot harder than what it was before. Maybe its just me, but not really noticeable overall. Once again though, I am happy with what I have gained though.

Old firing pin w/ 10a fuse mod
Panasonic CGR w/ .89Ω coil
3.70v / 3.33v <.37
4.24v / 3.76v <.48

New firing pin and spring
Panasonic CGR w/ .89Ω coil
3.70v / 3.39 <.31 (+.06)
4.24v / 3.88v <.36 (+.12)

I believe your voltage drop is minimized because you were running a fuze in your original set up which is more efficient than the new spring.

I don't think you understood the question. I was getting .11 more voltage drop between fresh and used battery with the 10a fuse... It is only .05 now that I did the upgrade...

You already had it modded. Not sure just what you expected to gain.

Can someone link this fuse mod please?

Maybe some difference in the 2 batteries? Or is it the same battery.

I knew I would gain some of the VD back when I switched to the new kits, same as others have...

Yes, they were 2 different batteries. One was a fresh battery, (4.24v), and the other was used, (3.70v), but couldn't understand why the VD was a .11 difference and wondered if anyone could enlighten me to that. That was all... Same batteries with new kit installed and only .05 VD difference...

I cannot tell from this if you tested the batteries to see how much of the drop is internal to the battery. Each battery has an internal resistance and under load this will create a V-drop, each battery is different so it's not uncommon for tests with different batteries to show different results.

Take a voltage reading directly from the batteries positive and negative post while firing a coil. The difference between this and the battery when not firing coil is the voltage drop happening inside the battery.

I will do that and see what I come up with. I need to get some probes for my meter to that. That was the only thing I couldn't test at the time. Thanks FB...

I have since put the spent battery on the charger and will test again when it is charged up later on today...

Are the batteries the exact same age with the exact same number of cycles? Seems any number of things could explain this.

 

[Filthy-Beast]

The other thing is as amps increase voltage drop will also increase.

So the 3.7 volts on a .89 ohm coil will pull 4.1 amps and 4.24 volts on the same coil will pull 4.7 amps.

Yeah, same age / cycles...

This makes sense to me. Never though about the fully charged battery pulling more amps. I did the test with an inline tester and also a handheld tester both and identical results from both... Thanks again FB...

Dave! Get the ego brother... Heck, get a blu! Just not the stink-sticks!

What exactly do you need? What parts?

The new kits should be up tomorrow.

Definitely grab an ego or some disposables before you grab some smokes, they'll taste like crap anyway.

The cardinal rule of vaping. Backups to backups to backups.

^this... I have lots of rebuild parts i could send you.... Just dont go back to cigs!

Man, I forgot how awesome everyone here is. I would have definitely checked back sooner

I just put my order in for the upgrade kit and managed to find an old ego I had laying around.

Thanks a ton though guys, vape on
