  • RE: BQ25504: why does my energy harvester not work? What am I doing wrong?

    Regarding 1, the boards looks good. Regarding 2, if the battery is attached at VBAT (or VSTOR), the cold start circuit has to charge both the VSTOR capacitor and then, through the internal PFET's body diode, the battery at VBAT if VSTOR is not shorted…
