MEGAphone Battery Management and Energy Harvesting Module

This post has turned into a bit of an epic, as it turned out to have a couple of modules (solar MPPT tracker and prioritised power input selection and over-voltage and reverse-polarity protection) that took quite a bit more effort to get right. So, we have a DC:DC regulator. Now we need a way to get energy into the battery. This module has a few more requirements, because of the different energy…
