    I'm in need of a miniaturized NiMH charger circuit. The circuit needs to fit within a 45 mm * 11 mm rectangle.
    The circuit will need to be able to sense when the 2 NiMH batteries are full, automatically cut charging power and to the user indicate full battery via an LED light.
    Supplied power will need to come from a USB-C connection, 5 volt.

    Is this even remotely possible to achieve?

    Ah yes. The link was to show the size is possible. Also much smaller.
    You just have to search and read the description.
    You can also find 2 or 4 cell chargers that you can cannibalise for the PCB.

    Whoa, that might just be it! It might just fit. Thanks a bunch!
    One step closer to production of my electric clipper to come.
