Charging battery via external 5V power source?



  • Hi,

    I am making a custom back for my Core 2 and I would like to add wireless charging to it, by connecting a wireless coil such as this:

    I know that core2 an integrated battery charging circuit.
    Do I understand correctly that it should be enough to connect the wireless charger to the 5V gpio pin? Or does the BAT GPIO charge the internal battery as well?
