Assuming, that my comment on patch 14 works POWER_SUPPLY_PROP_VOLTAGE_MAX_DESIGN is required in the fuel-gauge driver instead. As far as I understand it the charger voltage was too high for your device anyways, so that you capped it at 4.3V. So I assume, that you can just provide it via device properties.
