Vamo help - Power slowly dies

[kdubbie]

So, I just got my new Vamo V2 5 days ago and new batteries at the same time. Out of nowhere tonight, I noticed that if hold the fire button down for more than 2 or 3 seconds, the power slowly fades to point where it stops firing.

When I first got the device, regardless of the ohms on my delivery device, the rattle snake was always continuous and very loud

Now, regardless of the ohms on my delivery device, If I set the volts down low to 3.0-3.5, I get next to no power, and only fires for about 4-5 seconds before it dies. If I up the volts to 4.5 and higher, I hear the rattle snake loudly, but then it starts to fade and eventually dies out.

I did noticed i was on NO1 mode ... which I have no idea how it was set to that because I remember distinctly setting it to NO2.

The ohms meter is working correctly.

I tried a number of different delivery devices, pro-tank, viva nova, kanger evod, t3, mt3, and a couple of of carto tanks.

I also tried cleaning out the 510 connector and noticed there was a lot of black stuff on the paper towel I was using, is that corrosion of some kind?

I find this very strange because up until about an hour ago, it was working fine, loud rattle snake sound for as long I pressed the fire button ... Now every time, the power just dies out after 5 seconds or so.

What can it be?

The batteries I am using are: Panasonic NCR18650A Rechargeable 3100mAh 3.7V 18650 Li-ion Batteries, they are unprotected and I never let them get below 3.4 volts before I recharged them.

Any help would be greatly appreciated.

Thanks

Ok, I just tried something a new boge 510 cartomizer and the power didn't die on that, and it didn't die on my MT3 also ... Anyone have experience with the Vamo slowly dying on the pro-tank, viva nova (fasttech viva nova),

lets get it over with....
"should have bought a provari"

there. now no one else needs to say it. only real advice needs to be said now. he wants to know how to fix his set up not what you think he should have bought

i have two theories here

1. clean out the inside with 99% isopropanol alcohol. allow it to dry completely before installing a battery. then, stretch out that bottom spring. that will solve most connection issues. i work at a b&m, we see this a lot with the vamo

2. those batteries dont agree with the vamo. try throwing some imr batteries in there. also, the vamo isnt friendly with flat tops all the time. i suggest aw imr's 2000 mah. they last freakishly long for a 2000 mah battery.

try whatever one is easier first, then try the other. hope that helps.

p.s. seriously, no "shoulda bought mod x"

I use Vision vivi novas all the time and have had no issues with them on the Vamo in over 7 months. It sounds like the centre pins on your protank and knock off vivis may not be connecting properly - so its losing the connection. You could try gently pulling down the centre poin on a vivi and try it again.
Either that or the battery is giving you problems. Its not the recommended battery for a Vamo - an unprotected Li-ion is a safety risk. You really should be using an IMR - like AW IMR or Efest IMR - the Panasonic CGR18650CH is also a good one - all those batteries have safer chemistry, handle high drain and have proved to work well in these mods.

correct me if im wrong, but the cgr is protected, and vamos hate protected batteries.

You're wrong - the Panasonic CGR18650CH is an unprotected hybrid. Lots of people use them with their vv/vw mods.

Peeps! I use a ProVari and my Vamo (V3) and absolutely LOVE both! 4-5 seconds...(?) Why? I just don't have any need to draw that long. Raise the voltage a bit.

Sounds like contact fatigue. As stated clean contacts, stretch spring. check center pins.
Baring that there may be an internal failure.

Panasonic CGR18650CH seem to work perfectly in my Vamo.

i didnt realize the ch were the unprotected ones. i knocg they are some protected cg batteries florating around that would dislike being in a vamo

A google search would show you. Protected batteries tend to not work in Vamos, and are not suitable. The Panasonic CGR18650CH is a hybrid and is sometimes called an IMR. Like IMRs it is unprotected but actually has safer chemistry. It is one of the best batteries out for vv/vw devices and many vapers use them.

yes i know all about that battery, but i was also too lay to check if the battery he had was the protected or unprotected one at 3am lol. thats why i said its only a theory in my op. i still think he should try a different battery if cleaning the contacts and streching the spring does nothing

 

[Thrasher]

i would add stay out of No1 mode there is a good chance the average voltage measurement is not helping. and could drop off or spike at anytime.

Thanks for the tips, I will try a new battery, but they do work well with my carto tank and mt3. When you say isopropanol alcohol, do you mean isopropyl? Should I clean the inside of tube all the way to the bottom where the electronics are?

I read a couple of posts that say you can use a small flat head screwdriver to raise the center pin, but that was for when the ohms were reading 9.9 with an atty attached. My buttons work fine, they show the correct ohms, battery life and can go back and forth from volts to watts. Can raising the center pin help my situation?

Also, I noticed that when I cleaned out the 510 connector, there was a lot of stuff on the paper towel, is that just from the heat?

Thanks

Ok - but no, you didn't know about the the Panasonic CGR18650CH. I mentioned it and you were of the impression cgrs are protected, and asked if that was the case. Its not protected, its a hybrid.

Lets go back to the beginning - you have the wrong kind of batteries. They work with some things and not with others.
Also it seems your Vamo needs cleaning on the contacts - which you've been doing.
I tend to think the centre pins on the attachments are probably not the issue now - because you aren't getting a 9.9 reading.
Get some decent batteries, put them the Vamo with the contacts cleaned.
The black stuff could be from the manufacturing process. Give the threads a clean too. I had some black sooty sort of stuff on a mech mod I bought once. It happens. If there is other stuff - no, shouldn't be from the heat. You may have a leaking attachment.

You need to run the Vamo right. If you have an issue with running it right then return it. But first get it up and running cleaned and with a good quality power source.

Some are, I wasnt sure about the ch. I'm not trying to debate back and forth with you over whether or not I knew about a battery i don't plan on using ever

Then please stop beating a dead horse and move on. I mentioned Panasonic CGR18650CH for the OPs benefit. There are no Panasonic CGR18650CH that are protected. They are unprotected hybrids. They are also excellent batteries capable of high drain.

First, I mainly use IMR batteries in my VAMO without an issue. I do use CGRs and ICRs for backup and my VAMO works fine with them.

Second, the VAMO uses pulse modulation and has a 5 second cutoff - so if its cutting off at around that interval, its usual.

Third, I use both flat top and button tops in my VAMO without an issue. I admit I use the flat tops more but that's only because I prefer to use my button tops in my telescoping mods.

I doubt its about flat top or button top because the connection isn't being competely lost.
Your Vamo may work with ICRs but they aren't recommended. Some people have had problems with certain batteries in the Vamo - then some say they don't. What we do know is that IMRs or the Panny CGRs are not problematic and are the recommended ones to use. If I'm putting something up to my face that often I want to be as safe as I can with it.
I don't see how pulse width modulation would be the issue - the cut off could be, but what the OP is noticing is not a cut off but a dying out of power where before he had fuller power. The Vamo has a 10 second cut off - that's plenty of time to notice if the power has dropped. So I'm thinking that the cut off is not itself the issue.

Stretch the bottom spring and get new fresh safe chemistry batts,simple.
