    How to reset it?

    I am sure the timer is for elapsed charge and discharge time. You can use that info to determine how much capacity your cell has.

    MP3 player is a GPD2856c chip

  11. Avataaar/Circle Created with python_avatars Leberkas Semmel says:

    I go the same (or very similar) board, and the 8-pin chip was a 8002 amplifier. Yes, they did a very poor job on mine with removing the part numbers.

    Anyhow can we get the input audio connection in this circuit, as it don't support Bluetooth
