    Ordered another Yuasa battery for the owner recently.

    In 2019, I ordered the same model for myself.
    On this occasion, several changes with the design,
  2. Speaker - Repair

    • Output drivers (MOS-FET transistors) and Filter (coils)
      One pair of transistors connects one pin of the speaker to either GND or VBAT. The IC U2 ensures that two opposing transistors are never conducting
