This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Open any lithium battery pack and you’d find those cylindrical lithium cells. Even a Tesla battery has those. Only things that need to be flat like a laptop or a phone use a pouch battery.
On older laptops they used cylindrical cells too. On mine, you can clearly nake out the shape of the housing on the removable battery.
Used to repurpose the individual cells of laptop batteries for ecig batteries. The cells were 18650s, same as most customizable ecig mods use.
