Whoah, no need to get butthurt.
Clearly it isn't as good as the Provari if it can't even perform basic tasks like actually regulating voltage properly.
Feel free to rage about me being a fanboy now.

I'm not sure where you get "rage" and "butthurt" from my post, but I do think that my not-so-subtle allusion to "fanboyism" is well justified by the statement "I really don't even see how there's a market for it, you can get a Provari for ~$30 more". If that is not a fanboy-type statement, I'll have to go back to the Urban Dictionary and do some poking around.
And now, after your latest post, I think you're beginning to fit into the appelation like a pea in a pod:
"Clearly it isn't as good as the Provari if it can't even perform basic tasks like actually regulating voltage properly".
What's "clear" to you, remains "debatable" to me; but that said, I'd rather vape than debate about whose APV is "clearly" the best.
You, my good man, are talking like a fanboy. Sorry to rage at you like that.

Meh!
Getting this back on topic...
$128 for a Provari look-and-feel alike? No thanks. I'll pay that bit extra for the real thing.
Now, if they dropped the price to less than US$100 it might start to look a whole lot more attractive.
BUT - it's still a stacked-battery mod that seems to have some kinks to be ironed out.
Great video, as always, Phil - many thanks!

If you think pointing out that a better made, better functioning device can be had for a tiny bit more money makes me a fanboy then I guess I must be.
Continue your nonsensical babble.
The provari is the mod that is half as powerful isn't it limited at high volts to some ultra low wattage. It seems the amp switch can do more then twice if not three the wattage on a 3 coil carto at 6v. Just seems there are alot of fan boys on this thread.
Get any mod you want
It is a free market. I just don't get people arguing that a more powerful cheaper mod is inferior.
It is inferior if it's not even doing what it's supposed to do.
When I set a device to 5v I'd kinda like it to put out 5v, but maybe that's just me.

Just watched the Video and Vmax looks spot on for the money,Solid looking with up to date electronics, a few minor issues,but that is the same with every PV on the Market 
Phil. hope you don't mind me chiming in here....
I dunno guys. The stacked battery safety issue is a very big one for me. When a short happens, it's really really bad- presumably regardless of battery chemistry.
So in a sense, this new mod and the Buzz Pro have kinda of lost me at the outset. This is simply because as a systems engineer with an electronics background, Murphy's Law applies to all designs. If anything can go wrong it will. If the electronics fail, a physical short happens, or a battery has an internal fault, the fact that the batteries are in series usually creates a pipe bomb effect.
Even in a mechanical mod, these occurrences are rare. But they do happen. And we hear of more incidents now that there is an order of magnitude increase in the number of stack-capable mods in consumers hands.
Back in the day... the following was reported:
Unprotected CR2 Batteries Blow up the Detonator / Burn Leg
Now someone will point out that the batteries were unprotected in that example. But it serves as an example of what *can* happen.
It needs to be pointed out that protection circuits on protected batteries are not designed to pass 8.4v (the top of a stacked LiON charge) or even 6.4v (the bottom of the charge) when stacked. Safer chemistry batteries might be an option, assuming the stacked nature of the circuit doesn't drive one (or both) of the batteries to a temperature that forces an explosive state (Even IMR batteries at high enough heat can go critical).
The V-Max apparently has a protection circuit built in like the Provari. But the issue I have with this is that with this system we are one short circuit away from a dangerous situation.
True.. the design may be setup with the best possible protections. But that the same time: "If anything can go wrong- it will".
So it's been my preferences to avoid stacked battery mods. It just doesn't seem worth the (minuscule) risk, or advantageous from an industry standpoint to support what I consider to be a less than optimum design. Especially considering the availability of boost chips that perform in the high 90% level of efficiency and single batteries which can supply the needed current.
So those are my thoughts. I've often toyed with reviewing a stacked battery VV mod. However, that would mean I needed to own it.
I reserve the right revise my opinion in the future.

Sorry I dont get the Link or relevance between the Battery,s you mention & the Vmax I thought they state only use IMR (safe) battery,s ?????

As I stated in the post:

Safer chemistry batteries might be an option, assuming the stacked nature of the circuit doesn't drive one (or both) of the batteries to a temperature that forces an explosive state (Even IMR batteries at high enough heat can go critical).
I am by no means an expert, but the stacked battery mod vs single battery mod is an argument that goes quite a bit deeper than this. One side says stacked batteries are bad, 2x the batteries means 2x the likelihood of a battery malfunctioning. The other side says "What is more stressful on a battery, stepping up and drawing more current to get more voltage, or stepping down and regulating?". Both sides have merit and at the end of the day it's up to YOU what you want to use. Mods have exploded, this is true. How many mods with PCB regulators have exploded? How many provaris? How many buzz pros? Just thinking out loud here, not trying to .... heads with ya cozzi.
No offense taken it's a discussion that needs to be had.
The way you characterize my comments is not understanding what I'm saying. It's a complex issue to be sure.
There have been reports of a Provari melting down. However it *baked* rather than exploded because of the nature of an IMR battery. My point is that stacked batteries, no matter what the chemistry, represent more danger under a short circuit condition. And additionally that in a stacked configuration a protection circuit, which is designed for the voltage and current of a single battery, will not offer protection.
Now on mods like the Buzz Pro or this new V-Max- the protection is supposedly in the electronics. But this doesn't protect against a physical short or a battery fault.
So the shorter version of my point is simply this: Given the relative safety of IMR batteries, and their current capacity it's confusing to me why anyone would design a stacked battery mod given the additional risk (and explosiveness) of two batteries, Vs. one.
I think a lot of people (including myself) have not considered that the protection circuit sitting on top of a protected battery wouldn't be sufficient for a stacked configuration. Protected means protected, right? A good point to think about.
In the case of the Buzz Pro (or Infinity Pro), both the protection circuitry of the battery and the protection circuitry of the Buzz itself would have to fail for something bad to happen. In the rare chance that happens, vents built in to the units will allow gas to escape the unit so pressure does not build up. I'm really not worried about it. There's a greater chance of a lighter exploding in your pocket or you burning your house down from a lit cigarette.
And it can happen on any device, including devices that use a single battery like the Provari, which it reportedly has.

For the record, I have not heard of a battery exploding in any of the other popular VV mods discussed here (i.e. Lavatube, Buzz/Infinity Pro).
Why would high voltage be a problem for protection circuits?
Same for any device.
Don't boost circuits stress batteries?
Great review!! Lots of information, and easy to understand. I will proli watch it again once I have mine in my hand. I want to let u know too that I tried a few times to watch it and it would not play. This time no problem, so that saves the viewer lots of frustration!
Well done! can't wait to get mine, it will not be my first vv, but will be my first tube mod. I am looking forward to it.
