Why in the world would you need/want to use 15W or 6V ?
If it's not dangerous, then why does EVERYONE (including all the reviewers and manufacturers) advise against it ?
Is it really that much more superior to a 18650 ? Anyone else tried this ?

I would like to apologize if my post seems to be encouraging people to stack their batts. I'm just relating my experience on it.
Stacked batteries can be bad when they're not equal in state of charge,age,type and internal resistance. It's when one is depleted sooner than the other and then gets 'reversed charged' by the other when under load(since they're connected in series). The higher the current/amps, the worse it is. Which is why RC batt packs that are more than 3.7v(1 cell) have balance charging leads in addition to the main leads and are meant to be charged using a balanced charger(most hobby chargers are nowadays)
I would advise against stacking in mechs due to their unprotected high current draw and any other than IMRs. Regulated devices won't fire below a certain voltage. In the case of the SVD it's 4.6-6.5 in stacked mode if I'm not mistaken. So as long as both the batts are of equal charge/age/type, reverse charging shouldn't happen when the SVD shuts off.
I will swap batts when it's indicated 7.2v on the SVD. All my 4 sets of AW IMR 18350 are matched for capacity and IR.
As for superior performance, have a look here

As i remembered, the SVD manual does state to stack batts for improved performance?
As for 15w/6v vaping, here's my brief story,or 'journey',
I started vaping after 30+yrs of smoking stinkies with the well known ego-t + CE4. Although it kind of worked to steer me away from analogs, it wasn't really happening. I was sucking and dragging till concave cheeks to get any feel of it.
I was determined to never light up a stinky, so I thought, upgrade time, maybe I should get a VV/VW device so I can turn up power and get some warmth and thickness. Avoided mechs due to consistency and battery dependent, eventhough they have potentially more power.
So,got an Evic, gradually dial higher power and hit burnt taste at 7w on the CE4. Bought some ViviNovas and over 8watts it's burnt city again but still not giving that satisfaction feeling. Just for the record,all my juices are tobacco flavored as it's supposed to replace stinkies.
Until the day I tried cotton wicks in the vivis, I can crank to the Evic's max of 11watts without any burnt taste and that was like a huge leap forward to me in terms of feel.
As I begin using drippers, immediately it dawns on me that 11w isn't quite there for me. So begins the journey of microcoils and low(1.2) to hi(2.2) ohm within the evic's range to squeeze max efficiency, but there's only so much the evic can give, plus it doesn't even deliver the full 11w, more like 10w.
One fine day, got to try a provari, set to 5.7v for my rda(IGO-W 2.2ohm single microcoil/cotton), I got my most satisfying vape at that time, the Evic was no where near at it's maxed out 11watts. So, it confirmed to me that more power is what I need.
The SVD with stacked batts really performed to my expectations. I find it very hard to pick up the Evic nowadays. I'm not saying everyone should vape at high power. Sometimes I wish I can be happy at 7-8watts which got the advantage of more freedom in APV/battery choices.
Now thinking of a DNA20 mod
