    As someone who has built solar battery packs, that’s not how batteries work. They have a single connection (positive and negative), not a charge and separate discharge port. If the charge voltage is the same as the battery voltage, it goes directly to the device.

    The only problem is that you can’t keep the battery at 80% charged in this mode, which would be better for battery life while it’s not used.
