Firstly, kudos to all participants in this awsome project.
Secondly, as there has been some talk about along the way upgrade options, is it possible to bump up the current design into 192VDC nominal (for 48V x 4 subpacks charging), I think it has been mentioned by Paul that by mosfet/diode/caps direct replacement "only" it can go as high as 180V @ 750A. I'd say the amperage is not that important criteria as max. voltage in this regard, as long as it still hovers around ~100kW peak, e.g. 192V @ 550A, thanks for giving it some thought.
