Re: Batteries in the pocket, eh?
The 'box mod' name is a hangover from when people used to have to make their own devices to power self-built atomisers that required more power than what simple batteries available at the time could provide (typically under 15w).
'Box mod' has just become an industry term for them - really, what you're thinking of is a 'series box' or similar unregulated device, which is a far more serious bit of kit.
As for the two cells, 200w, there's a lot of pissing about used to get 200w out of a 2-cell device, but it's not a case of it draws straight from the cells - it uses various stepup/step down techniques, at restricted ohmages, to reach that level of power.
Again, there's millions of devices out there, and very few failures (and even fewer catastrophic device failures - almost all are loose cells in the pocket type affairs).
There's a load of electronics shenanigans that are a bit above my level of expertise to answer on the subject of 200w devices with two cells, but there are a few explanations on the internet as to how it's acheived safely - such as not letting the device provide that much power once the cells get below 4v (it'll restrict you to 150, then 100, etc as the voltage drops).
