So what would the wattage be limited to with two18650s in parallel then? 60? Personally, since I'm pretty much a Ni200 RTA kind of vaper, 20 watts is plenty. The problem is that's just me and I was saying that many others want a lot more power and would be put off by not getting to utilize the full 200W or even anything less than 100W, which is why they've, at this point, decided to go with SX instead of DNA200- to make their customers happy and please as many as possible. Even having the SX in parallel was a decision they made to choose long battery life over higher wattage.
We talking DNA200 or SX-350J? No way to make parallel work on a DNA200, as I mentioned.
With the SX-350J in parallel, since the amp draw is halved per battery, they're allowing 100 watts/joules in the version that's installed in the SX Flask, compared to 75w for the single battery SX Mini M Class. But it won't support the full 150 that Yihi will allow in dual series battery mode because there's not enough voltage output.
The reason they chose parallel is partly due to a BIT better battery life (seriously, dual serial mods are
very close in actual run time to dual parallel mods, all else being equal), but it was primarily to avoid having to make even more extensive modifications to the Flask's basic design (it depends on the enclosure for common grounding, they'd need to build a "sled" of some sorts to isolate the batteries, then wire them in series and ground the sled, and they're already cramped for space as it is).
