My opinion is that 2x18350 will give you strong hits and performance and with 1x18650 you ll get duration

I find a noticeable difference in the vape when stacking 18350s vs a single 18650 in the VAMO. Battery life is a little less but the vape is definitely stronger (they kind of allude to this by telling you to use mode 1 with single batteries and mode 2/RMS with stacked).
The difference is much less noticeable and may not exist at all in the SVD.

Ummm, I don't know of any instructions (unofficial OR official) that recommend running the Vamo in Mode 1. It's one of the reasons why the Vamo v3 is Mode 2 only.
Power is still there even if regulated. It must go somewhere. Vamo likely spools off the excess and it is used up as heat.
I know from use (2)x 18350 stacked will not last as long as (1) 18650 in my Vamo.

I am sure you can find some mechs out there that do side by's
I think the market is all about the tube look. I have a Vamo V3 currently, but if I can find a box mod that has the features of my Vamo, and can rock two 18650s, I'd probably go that route for my next device.

With a single battery, regardless of the voltage setting, the chip boosts the voltage up to 6v and then cycles the power on and off quickly to simulate lower voltages. It's the same concept of "pumping" the button on a mechanical mod, pressing and releasing it quickly over and over while hitting it, so that you tone down the vape.
So the excess power isn't dumped as heat and wasted, the coil receives the full boosted voltage, but only for split seconds between moments of no voltage at all, so it averages out to be similar to the voltage you have it set to.
Well, if the PV isn't rated for stacked batteries, don't use em stacked.
Also, it's stacked batteries when shorted that are the most iffy.
That said, the voltage is squared in the power calculations. Higher volts are supposed to be more efficient. This isn't accounting for device efficiency nor the differences in total battery mAh.
I use stacked 14500 Li Ion's (protected, and in a bucking voltage regulated vv mod) every day. They last a day and a half. That's at 4.8 ish volts and around 2.8-3.0 ohms.
The voltage regulator SHOULD be more efficient when bucking than when boosting <---- kind of a guess and it varies by device design.
I'm not sure I'm fond of stacking batteries in any tube mod though. The thing is...with stacking batteries you're limited to the max-amp rating of a SINGLE battery. So that's when shorts at the higher voltage exceed the C rating of the battery quicker (all shorts exceed the rating, but this would be double the oomph due to stacking).
That's why I use protected batteries in my box mod. That gives me THREE trip points...one on each battery and one for the voltage regulator that has over-current protection. Also the box mod can't build up internal pressure because the back just slides off.
Anyway, OP. A lot depends on the efficiency of the mod's circuits. And features cost. Also safety costs...IMR's hold less charge but are required for booster mods.
Mine, as a buck mod, is more efficient at higher voltages. However, it can't boost. And has no frills.
Get a few spare 18650's. Good ones. And maybe a plastic carrying case or an old pill bottle or three.
EE's could tell you more. Theoretically, higher voltage (and associated higher ohms to similar watts not more watts) are more efficient. Design matters. But safety counts too.

It was there when I ordered the unit. Now the place I bought ti from tells you stacking batteries voids the warranty. Still, the point is there was a noticeable difference between stacking and single batteries in the previous VAMO, at least at higher voltages.
The other thing I should mention...
When stacking batteries, make dang sure the voltages are matched. What happens is that if say one cell is charged and the other one isn't charged well, the electricity tries to "level out" and it can cause an over-heat situation of some sort. I'm not real sure on this, but there's lots of notes here on ECF about having cells matched/charged properly. Even wear them evenly. People use them in matched pairs and label them in pairs. And they swap leading/trailing around too.
I always use mine in sets. I also make sure both are charged properly when they come off the charger.
And if you're doing SLR stuff, you don't want to go anywhere near stacked batteries...IMHO.
Of course, that SLR stuff doesn't apply to a protected APV with circuitry.

There is a definite difference in performance between using an 18650 and two 18350 batteries in the Vamo when vaping DCC's. I've read and found to be true, the 18650's will not go above about 11 watts when using DCC's. With the two 18350's there is no limitation and the warmth and fullness of the vaper is obvious in comparison to the 18650. The standard 18650 will provide a little longer time on charge but not enough to make much difference from my experience.
i use all 3 setups on my vamo regularely. single 18650 gives longest vape time. two 18350s stacked gives slightly shorter times but is better able to keep up with higher wattages. single 18350 is just more convenient but offers no other advantage than reducing the size of the tube.
