Hello, I have a VAMO (v5/v3?) idk which version exactly, but last night I was using my PT2 with it with a fresh coil and charged battery and all was well, set it down for half an hour or so picked it back up and was getting burnt pulls, today I cleaned my tank refilled with juice and another fresh coil and am now getting burnt pulls after 10mins or so, my question is why? my most recent coil I have in now is 2.5Ohm and I didn't even get to 3.5V before tasting burnt, if I put the tank on my ego style battery which I believe fires at 3.7V all is well, So my question is why am I unable to crank up the voltage to even 3.7V? Seems like with all my tanks I can't turn the voltage up very high at all usually have to stay between 3-3.4V no matter what resistance the coil has
Burnt Taste question..

burnt taste is usually due to the wick drying out but since you stated that the same tank works on another base I would start looking at the vamo for issues.
Have you checked the ohms of the coil while on the vamo?
Has the pull (puff) factor changed ( harder easier?)
Are you using the same juice?
Does the Vamo actually show a change in the voltage when you adjust it?
Sometimes, if you tighten the tank down too firmly, it compresses the coil tube insulator and reduces the airflow, causing a less than optimal vaporizing sometimes leading to a burnt flavor

It could depend on which version of the Vamo you really have and what mode it's in. Try holding down either of the two small settings buttons for a full 14 seconds - no less - and see what the display reports. On a V2 and some V3's it has two operating modes: N01 (PWM) or N02 (RMS). The PWM gives a much harsher vape even at lower voltages - you want it in RMS mode. If it's the type that has this switchable mode the display will read something at the end of 14 seconds reporting it's in one of those two modes.
I have a v3, and yes I've been using the same juice in there, could it have anything to do with the battery? It doesn't seem to happen as often with my 18650 vs the 350 efest. and yeah I've checked the Ohms while on the vamo itself, and the puff/draw factor hasn't changed and it does show a change in voltage when adjusted. and I just tried holding one of the smaller buttons for 14 seconds and it showed RMS output, does that mean it changed to RMS now?
It gets a little weird with Vamo's about which version has 2 modes - or not. The V2 definitely has both modes. The V3 was only supposed to have RMS mode - but some do and some don't - like yours.
The difference is Pulse Width Modulation has a very rough way of creating an average voltage. That's why it can also taste rough. RMS mode puts a filter on that rough voltage, smoothing out all the up's and downs of what PWM devices do to provide that "averaged" voltage. That's putting it very much in layman's terms.
If you ever want to check it just keep in mind that after you have pressed the settings button for that 14 seconds, whatever the display shows is the mode you are in now - what it just changed to - not the mode you used to be in. On the V2 changing the setting drops your voltage back to 3.0 volts (or wattage if in wattage mode) - so you have to move your voltage or wattage back up to where you want it after changing the mode it's operating in.

Thanks again for the help, one last question though - I just changed batteries out and held one of the buttons for 14sec to double check what mode it's in, and this time after holding the button it showed Mean Output, is that similar to RMS? or do I have a v5 or something?
Change it back. If it said Mean you are in Mean mode. Hold it again until it says RMS.
I see, I changed it back so it is in RMS mode, just wasn't sure what mean mode meant. And I'm 99% sure I have a v3, I did have a gun metal v5 (v2 styling with the v3 top removable piece) but I took it back to my local shop, I didn't like all the fingerprints and residue that showed on it and got a v3 instead. I would post a picture but I have no idea where my camera is =\
In non tech speak "Mean" is a less than perfect way of measuring the output that puts out more volts/watts than the display shows.

Mean is the unfiltered PWM mode. You want it in RMS mode to take the harshenss out of things.
