need help (new Vamo) I'm crying here

[kiwivap]

Slightly off topic, but as a side note - as expected the Vamo battery thread has people also reporting that trustfires and ultrafires don't work with the Vamo: http://www.e-cigarette-forum.com/forum/vamo/355592-vamo-battery-thread.html

If you know some-one getting a Vamo maybe give them a heads up on avoiding those batts.

Is there yet a thread about people using imr's such as the panasonic hybrid 2250mah 10amp 18650 batteries, 18650 AW's (orange or black) or efest 18350's (either in single use or stacked) that are getting a "Lo v" message after two hour of use?

I just ask since it seems relevant to the OP's question and that I've seen it come up in various Vamo subforums, but has yet to be addressed and instead battery conversations ensue.

Why don't you go and look for a thread?

Was just reading an interesting fix to a problem similar to the OP's, from here: http://www.e-cigarette-forum.com/fo...tna-vv-vw-owners-here-yet-77.html#post8069840

OK, self solving problem.

I don't know what the particular issue is with the board in my unit, but apparently if you put an overcharged single cell in it, it reads it as 2 cells with a total voltage that would be below its cutoff point for 2 cells. This batt was at 4.5 volts, and was apparently falling into this "hole". I can't come up with any other logical explanation for it, since the problem was very repeatable. One batt had 4.3v, and wroked fine, while the other had 4.5v and wouldn't fire.

So, I just ran it for a little while in dual 18350 mode, til I bled a little voltage off that one cell, now it works fine again. I'll have to keep a closer eye on my cheap POS charger from now on. I'm thinking a better charger is in my future.

However... just because the symptoms are similar or the same doesn't mean the cause is. There will be the odd defective unit. I do find it interesting that in the case I linked to above it was an overcharged battery causing the problem.
ETA: It's similar in showing the Lo-V with a charged battery.

I think you should reread what OP wrote. That is entirely different. My issue however was remarkably similar with the exception of the "Lo ohm" reading. Outside of that it was identical.

I was fortunate to get my money back. I actually bought my vamo off of the classified section here at ecf, but was lucky enough to get a refund and help the seller get a replacement for the faulty vamo; which he is planning on keeping after reading all of the positive things people have said on these vamo subforums.

My retort/rant was in response to the suggestions I received and have seen again given to the poor soul who started this thread. Unfortunately there is a fanboydom response as this pertains to the vamo and imr batteries. Not all batteries are created equal. I would rather have a high quality li-ion battery than a mediocre quality imr, but those are my prejudices and I am not one to regale people with these prejudices as they are going through an extraordinarily frustrating time when it comes to receiving an apv one has pawned after and may have had to wait weeks to get. I do believe that imr batteries are the smart choice as it relates to performance and safety, but not to the "Lo v" problem.

My response was fueled by my frustration with the ineptitude of people's ability to see past their fanboydom and actually help me out with my problem. I do believe that 98% of problems are user error and I initially welcomed responses as they pertained to batteries. I thought they were bull as it pertained to my problem and a product of imr fanboydom, but I appreciated them nonetheless. After I shelled out more than any Vamo cost in batteries (which did nothing to correct the issue), everyone was silent. I tried to see past that, but seeing someone else with the same problem I encountered being told the same nonsense is a bit infuriating. No one is acknowledging the problem I encountered nor the problem OP seems to be, but people are instead telling tales about their set-ups in order to make themselves feel as though they've made awesome, knowledgeable choices.

Fanboydom is frustrating when you receive a faulty product that is the celebration of fanboys (the Vamo) and it becomes incredibly more frustrating when these same people recommend fixes that exposes their other fanboy obsession (imr batteries; regardless of brand) and then offer no support once the recommendation of an imr does not fix the original problem/fault. It is incredibly more frustrating to see someone else encounter the same problem and see the same people give the same advice. It makes my head throb...

If you dont like the help and advise that vamo owners offer than just ignore it and figure it out yourself. Not every one has the same troubles or the same fix but any sugestions for things to try IMO is a big help. I for one love my vamo so if that makes me a "fanboy" so be it. I still like it.

I'm running High Drain Panasonic CGR18650CH 10A 18650 Batteries (the Grey ones). Only one so far and it's running fine, it's been in my vamo for over 2 hours with no problems whatsoever.
I'm vaping a VN cotton 2.4Ω @ 7w.
I think maybe there is actually something wrong with your vamo, I also read on a couple of other forums that TrustFires and UltraFires Do Not work, they seem with mess with the internals and although the Vamo lights up and may perhaps fire, it then shuts down. I can't testify to this myself as I don't own any TF's or UF's, needless to say I wouldn't be keen to risk it.

I appreciate advice and suggestions. I illustrated extensively how I used the advice. There was some sound reasoning behind using an IMR as well. That's why I procured some. Unfortunately it did not fix the problem, but it did help confirm that it was most likely a faulty unit. Unfortunately once the IMR's came there was no further suggestions and people with very similar problems are being given the same advice without the problem being acknowledged.

If you have issues with the other thread then I suggest you take them to the other thread. Continually name-calling people fanboys isn't necessary.

 

[kiwivap]

I didn't take offense, and am just pointing it is unnecessary to continually name-call.
I am suggesting you take your issue back to the other thread because you are giving one side of the story on this thread. A lot of people responded to you on the other thread up to the point where you said the person who sold it to you in the classifieds was taking it back and sorting it out for you.
Your issue was not the same as the OPs. Since the OP has said he has Efests already on the way, there is no harm in trying those with his Vamo to see if that eliminates the problem.

 

[LeAnn]

I had the same problem with my Z-Max and it was because I stacked two 18350's, I blew everytime, so now I only use one 18650 and have had no problems, I don't have a Vamo but maybe there is just two much power for the nova heads. It did it with my carto's too!

This would appear to fit in with an issue I found with the VAMO.
It seems to misread Resistance at higher voltages.

Using the same carto on each of 2 different VAMOs', I got the following identical results: (New VAMOs' and New Batteries)
1 x AW18650 IMR - Resistance = 1.5 ohms (both units)
2 x AW18350 IMR (stacked pair) Resistance = 1.7 ohms (both units)

Might not sound a lot, but it means that in VW RMS mode at 3.7v there is an extra 1.45 Watts of power drain.
(The VAMO would will increase the voltage to 3.95v to compensate for increased resistance - see post on Vamo thread for full explanation)


The only other things I can think of that might help this thread have all been said before:
1. Is it a v2 VAMO with the insulator ring in the battery housing ?
2. Does the endcap have the new 'longer' spring ?
3. Have you read the advisory from 'Health Cabin' not to use 'protected' batteries as a lot of them don't work ?

From my (Chinglish to English) re-write of Health Cabins VAMO Manual:
When a single battery's voltage is less than 3.2v or a stacked pair of 18350 batteries voltage is less than 6.4v, the screen will display LO v. This indicates that the batteries need charging.

When you use an atomizer at 1.2 ohms or less, the screen will display LO Ω.
The VAMO eGo APV will not work with atomizers less than 1.25 ohms.

 

[TrueNews]

When the atomizer has a short circuit, the screen will also display LO v

Hi true News,
Does this happen with higher ohms as well or just the lower resistances?

Hi kiwivap

Havn't tested that yet as the VAMO's are really Christmas Presents lol.
I have some Vivis' with higher resistance heads coming too so I will test as soon as I can.

My real concern is that the VAMO reads High Resistance with High Voltage.
If the opposite happens, and the VAMO reads Low Resistance with Low Voltage, then maybe LoV warnings could get triggered.
(from the info the OP gave, on his wattage, and resistance, I can't really see this happening though)

Reading the OP, I first thought that a 'burn in' of a new head might be necessary.
But on doing the math - 4v (6.7W) for a 2.4 ohm coil is about as low as you can go.
Maybe VW RMS mode is not the best mode for a burn in - especially if it is not reading carto resistance correcly.

Will catch up as soon as I have got my Chriisy Present and had chance to test it some more

TIP
Don't use LR atty's on dual 13550's - It is Vicious - 3 volts on the VAMO is not low enough for this setup.

 

[DrApex]

I believe people respond to their level of understanding of the problem.

More people understand battery problems and feel comfortable recommending a 10$ battery than replacement of your PV. Also, more often than not, batteries, and especially with APVs, cheap batteries are the problem.

So they may be battery fan boys, or they may just be trying to help out on a free, volunteer message board.

Hey all. I just received my Vamo and for 2 hr it worked perfect. Had it in RMS at 7.5 Watts. All of a sudden it stopped working and the coil that came in the Vivi Nova showed 'low ohms' then LO-V indicating short circuit. . I thought the coil popped so I installed a new one and it worked perfect and then did the same thing as the first. I tried 4 new heads and they all did the same thing. It would alternate from showing lo Ohms to LO-v (check showed 4.0 volt on batt). So in disgust I sat it down. I picked it up ten min later and the 2.8 ohm coil now showed 2.5 ohm (indicating the coils were not popping). So now if I let it sit for a few minutes the zero ohm head will rebound back up to 2.5 Ohm letting me hit it again only to drop again down to 0.0 Ohm. I am waiting on my XtarWP11 charger and efest batts so I was alternating using a Panasonic NCR18650 and a Panasonic CGR18650EA. The Vamo just now worked showing 0.0 Ohms LOL. Since the batts are fully charged, I think (but not certain)I have a defective unit. The only other thing it could be is the batts are not allowing enough amps? Any help would be highly appreciated. Oh, I tried posting this in the Vamo forum and it would not let me (drats!) After sending this post I picked it up and it shows 2.5ohms LOL

I noticed that my ViVi nova was not playing well with my vamo and grabbed my 510 to ego adaptor and it seemed to fix it. After some fiddling found that the center post was not making 100% contact with the ViVi nova so I pulled it up a bit, let the nova push it back down into place, and don't have an issue until I put on my phoenix (it push's the post back down).

 

[Edd Harbin]

Center post , center post , center post .

Had same problem after putting a ego adapter on mine . Center post pushed to far down . Used a dental pick to pull it up and fixed problem .

 

[Underwhelmed]

I had the low resistance error on my Vamo while using a 510 to eGo adapter and a Kanger T3.

Turns out that the Kanger had leaked liquid and the adapter isn't sealed, so the connection flooded and the Kanger was being read low.

Took everything apart, washed what could go under water and wiped the rest out with a napkin and everything was fine again.

 

[budynbuick]

Hey, all. I 'm the guy with the defective vamo. I got the replacement today and while it has none of the issues of the first, this one will not work in RMS LMAO! It vapes fine, gives proper Ohms, reads voltage properly, no flickering, the zero in off does not look like an 'a'. It looks like a zero LOL. Now, when I hold plus button for ten sec it reads n02 (not 002 as the first 0 reads like a n). No big deal (or is it?) but when I go to set the watts, it is still in V (AVG) The first was so ditzy, I could not get a puff. At least with this one I can puff on it. The pannys (2900 Mah) are working great. Been vaping for almost 3 hrs and it still reads 4.1. I have now received TWO bad Vamos in a row! The vendor (OKC) sent me a replacement before I sent the defective one back. She sent it on the 21st and I got it today the 24th. Great service but what is the deal with two bad ones in a row? Thanks to all that responded to my first post but I was denied access so I could not answer but it is obviously fixed now. BTW, the first one worked great in RMS mode. I snake bit Any ideas? Thanks again.
