I have completed a firmware MVP today. All features are functional. Battery cell number detection, cell voltage readings, balancing, USB PD discovery, auto selection of PD voltage for highest efficiency, auto calculation and setting of max charge voltage, and a basic command line interface for debugging.

I have tagged the release as v0.1-alpha.

In other news, I have placed the first order of production boards. They are Rev 3.0 and I'm calling this run a beta. They will go up for sale on Tindie. I plan on creating a machined aluminum case that will also serve as the heatsink. I will eventually put it up for sale as a finished product.
