Also, there are other risks with stacked batteries. It is very common, at least in every case when I have tried it, for one battery to discharge much faster than the other. This can be a dangerous situation. When one of the batteries goes below it's minimum charge level, it is still possible to keep vaping, especially with voltage regulated mods, without even knowing this is happening. One of the hassles of stacked batteries is to have to keep checking the batteries.

Power control with a single battery. The ability to change at whim is priceless.

With a protected battery this is NOT TRUE , they have an over discharge circuit in them ! FYI they also have a overcurrent protection circuit so over charging , undercharging and over current draw are covered in a protected battery .
I have never had to check stacked batteries after over a year of vaping on them so just throwing out un proven info does;nt cut it sorry .

Make sure to run a high drain battery in that thing please !

In my case there's no absolutely no question, vv is it for me. Not having to think about which atty or carto would go better with the power of this, or that mod just makes it so easy and simple...not to mentioned the money saved on collecting all these different attys and when we get away of the screw driver method of adjusting....which is happening now I think more people will be willing to find out the advantage for themselves.

Ok, this thread got my attention. Disregard my veteran status on the ECF, because I am new to mods and especially have no experience vaping above 5 voltz.

Im looking for a PV / ecig that will give me flavor with light to medium th... Would a VV Mod do this for me? To be more specific, I dont like dripping. I dont mind topping off every now and then if I have to.

Currently using a LR Mega Atty on my ego with the 2ml cartridge and find that its not hitting the flavor and the TH gets harsh often since it burns juice quick...

I just bought a juice fed mod to try with a LR standard size atty.. Hopefully I can get consistant performance... I hate getting the burnt flavor and harsh th which happens too often and gets anoying which makes me feel like buying a pack of analogs.

 

[Zen~]

I don't think in terms of voltage or resistance too much, because the truth of the matter is that the battery voltage and resistance of the atty are part of a bigger picture which is the result of the interaction between the two...

The factored result is wattage!

A vv device enables the true ability for variable wattage. A variable resistance atty would provide variable wattage as well.

Ultimately we are usinga power source to drive a load, but that load determines how much current will be demanded of the power source... The two are inextricably intertwined within the system. The end result of heating the coil in the atty coes from the wattage in the system.

That being said, there are several ways to arrive at a given wattage... An LR atty with a 3.7v may very well deliver the same wattage as a standard atty at 4.2v or a HR atty at 5.2.... With one caveat... that HR atty will probably produce more vapor at the same wattage because the HR atty will generally have a few more turns in the coil... Bigger coils will more readily heat the juice and voila'... More vapor at the same wattage!

Now, if a company were to develop a true variable wattage device with actual variable current limiting as well as variable voltage, both of which factor in determining the wattage, than said company will have introduced something quite unique... The ability to adjust both voltage and current delivery to whatever atty load happens to be present on the system... then it truly would be variable "hit".

If the device and controls were well-executed, I would buy that for certain.

At this point in my vaping experience I've tried and owned just about every mod/atty/carto out there. I've always sought the perfect vape...Once I tried a variable voltage I never used any of my other mods again...I've sold most of them off and will be VV only very shortly when my new mod arrives..I've found throat hit, vapor production, flavor, and atty/carto life much better with a variable voltage mod...I use attys/carto that ohm @ 3.0 and voltages from 4.1 to 4.5...They perform beautifully and the best part they don't blow after a few days..I'll never go back to a fixed voltage mod....

 

[Rhapsodies Fire]

I'm lazy....when I find an atomizer that fits my needs i get a ton of them. I am not into the fidgeting and fussing around. I want simple. That is what works for me and what helped me get away from the analogs. Thanks for asking! I admire that.

LR works for me. I've even used them on an eGo-type battery before I heard the buzz about that being a problem.
So, with that information in hand, I got an 18650 mod, which is not stressed by LR.

I am very glad you have been using stacked batteries without problems. While you are correct for protected batteries, many are using LiFePO4 and IMR batteries that do not have this protection circuitry, and while these supposedly will not vent with flame, they can vent. Even with protected batteries, the protection circuitry has been known to fail, especially with cheaper batteries. There is plenty of documentation available, I am not making this up. See here for one. Also do some searches on candlepowerforums.com.

Obviously, problems with stacked batteries are very uncommon, but they are a possibility. I am simply stating that this is one of the reasons that I prefer not to use stacked batteries in order to get HV.

 

[aprioristic]

After going to VV, I don't even want to vape non-VV anymore. IDK if it is just the fact that the current is regulated, but it makes vaping way better.

I got this guy's Tekk mod and it has a lot of advantages over what is out there I think.

Factor in that it includes batteries and charges through mini-usb (and can charge other things off it) -- for the price and it seems on par with other stuff out there. The downsides are that it is plastic and no choice of atty connector type (but I didn't ask).

 

[WillyB]

I'm not all that concerned about the small batteries blowing up, although, in most cases, they are being overstressed in order to get HV, so there is at least some level of risk. I am very happy with the performance of a big battery 3.7v and LR306, and I would not trade the long battery life of a 2600mAh+ 18650 & LR atty for less that 900mAh to get HV/VV.

But the thing is VV (variable volt) mods are also CV (constant volt), the same cannot be said about your set-up. Assuming the 18650 starts out at 3.8V (that's under load, what you are actually vaping at, fresh off the charger), that is rather temporary, basically with each drag the voltage will be sagging a tad.

With a regulated VV mod if you start at 3.8V during the entire session you will remain at 3.8V till the PV stops. This is something I'm used to, find quite desirable, and have come to expect. Yes there is a trade-off in overall vape times, but with a simple 18650 set-up, even though they can provide longer vapes times (of a sort), once they drop about 0.4V I end up swapping them out anyway. It's 3.8V I want, at 3.4V the WATTS (power/heat) have dropped by about 20%. I find that significant, noticeable and for me (and many others) a compromise that I don't want to make. After that point any vape time doesn't matter.

To each his own.

Good point. You guys are actually convincing me on VV, but only if I can get it with a big battery. Looking at the ProVari closely.

 

[BuzzKill]

There are several Mods you can make for CHEAP in the modders section to try it out and not be out much $$$ , take a look , that way can try it be out for very little cash and probably sell it if you do not like it !

 

[DC2]

I understand. I am aware of only one VV that uses a single larger battery. It uses one IMR 18490/18500 stock or an IMR 18650 with an extension cap. With this you get VV, long battery life, and none of the hassles and safety issues of stacked batteries. This would be the only way I would be interested in trying a VV mod. If I have to stack batteries to get VV or HV, I am not interested in the least.

This is my answer too.
I don't ever want to mess with having, using, or needing two batteries.

 

[Sorrid]

I agree with El Dee. I have several mods sitting over there on my desk looking very lonely ever since I got my first VV device a week ago.(the Buzz) The ability to tweak voltage to fine tune that atty/juice combo I am using at the moment is priceless. There is no way I can go back now.

For instance I bought 60ml of FSUSA RY4 a few months ago and no matter what atty/carto I used on 3.7 or 6v I just didn't like it. But on my Buzz set at about 4.3v it has become fantastic.(Glad I didn't throw it out now)

It is going to be an interesting year for hardware. We already have a few new VV(Infinity) and VW(Darwin) devices on the horizon and they are looking sweet indeed. Oh my poor wallet!

You've made me a very happy man Mike and we are looking forward to seeing what that little busy brain of yours can come up with next.

The reason I question this Idea and the paranoia is that I am hard pressed to find anything or any studies that show that stacked batteries that have protection have caused any problems !! , in the PAST there were issues BEFORE they put protection in them.

Your laptop has STACKED Li-ion batteries in it so does your TV remote ( primary ) , Garage door opener( primary ) , flashlight ( primary and or Li-ion ) and many other devices , RC cars use them as well !!

So as I said there is some old stuff out there from mainly misuse in a device that does NOT have protection built into it like many of the regulated mods ,the Older Mods that are purely mechanical still have this issue just slightly more than a regulated device .

FYI , if you have anything current please link me to it ! I would like to see the info.

 

[Zen~]

Most modern cordless power tools with LiOn batteries have stacked batteries... And these are pretty high current demand devices too... If we think about it, there's a long list of stacked battery items that most of us own.

I don't know where the mass hysteria came from... I do know of one case of stacked CR2 unprotected batteries leaving a pretty harsh case of flash-rash on the leg of the builder of the aptly named detonator mod... But there's no way of knowing in retrospect if the melt down was caused by a short in the flashlight mod or not. We may never know.

There's a thread around here about it. Are there any other cases of this sort out there?
