If you have the short battery extensions I think so...
The fasttech ones say they are shipping with 2 battery tubes
But I think you loose the ability to vary volt it...with 2 batteries the combined total voltage is a little over 7vdc, the regulator then allows you to change input down...with only a 3.7vdc that is the most voltage you will get out of it

I ordered a black VAMO V3 from FastTech and it came with a 2 extension tubes, one that fits an 18650 and one that fits an 18350. The 18350 tube is nice when it has to be in my pocket a lot because I'm moving around. It came with the 18650 tube screwed on and the 18350 tube was hiding under the packaging, almost missed it.
No you can still use variable voltage/variable wattage if you only use one 18350 or one 18650. Yes, true, you CAN stack 18350s in the vamo, but theres no benefit to doing so. Its the same as using one 18650.
The benefit of running one 18350 is smaller size. You do lose the extended vape time of a bigger battery though.
Stacking two 18350s is not the same as a single 18650. With one 18650 you get 3.3-4.1v for however long the battery is rated. With stacked 18650s you get 6.6-8.2v for however long the batteries are rated.
Batteries in series (stacking) increase the output voltage, current remains the same.

In single battery mode the Vamo boosts the voltage to 6 volts which is then pulse width modulated to provide an output that has the equivalent heating effect (RMS) of the voltage that it is set for (3.0 to 6.0 Volts). The big advantage of stacking is that it will push the full 15 watts with lower resistance devices, this is because it doesn't have to boost the voltage to get the 6.0 volts to start with instead it regulates the voltage down to 6 volts.
PWM (Pulse Width Modulation) is simply the time the output is on versus the time it's off expressed in percent of the on time, this is called the duty cycle.
25% duty cycle = 3.0 volts RMS (1.5 volts AVG), 50% duty cycle = 4.25 volts RMS (3.0 volts AVG), 100% duty cycle = 6.0 volts RMS (6.0 volts AVG).
From this you can see why you don't want to use AVG (NO1) mode; you would set the Vamo for 4.0 volts AVG but get the same heating effect as if it were set for 4.9 volts.
So in reality the Vamo always outputs 6.0 volts; we just tell it how long it's going to be on versus off and this happens 33.3 times per second. This is how the Z-max, V-max, SID, etc. all work. This is a cheap and dirty way to control the output which is why manufacturers do it and why they are cheaper than a ProVari and similar mods.
I rarely go over 10 watts so I have no need to stack batteries myself.
