A long idle period and I thought a lot over this and eventually decided to go for a STM32F103C8T6 microcontroller to control the system. I had initially thought of using an Arduino Nano but integrating a few libraries tends to fill up code space really fast, so there might not be enough room for expansion later. The IC itself is also available cheaply due to it being used in a lot of low cost dev boards from China, and I have a few spares lying so it'd be a good idea to engage them to work here.

I'm now beginning work over board layout of the charger section, although I'd seek some feedback on how many outputs you'd like to see from this power pack, after which I will complete the board and send it off to the fab.
