|Organized Schematic| In this session, I added some new ICs and organized the schematic. It took a couple of days of research to start picking a good IC for the battery Management System, but I settled on the LTC4015 from Analog Devices. The LTC4015 supports LiFePO4 battery chemistry and includes built-in power-path circuitry and MPPT for solar panels. I decided on a 2S2P (2 batteries in series, with each series having 2 batteries in parallel) to get good voltage and capacity.
