  23                 means that the battery is discharging.

  50 Date:           Januari 2021
  51 KernelVersion:  5.11
  52 Description:
  53                 To save battery current, the measurement system is disabled if
  54                 the battery is the only source of power. This affects all
  55                 voltage, current and temperature measurements.
  56                 Write a "1" to this to keep performing telemetry once every few
  57                 seconds, even when running on battery (as reported by the online
  58                 property, which is "1" when external power is available and "0"
  59                 when the system runs on battery).

  66 Date:           Januari 2021
  67 KernelVersion:  5.11
  68 Description:
  69                 The charger will normally drain the battery while inactive,
  70                 typically drawing about 54 microamps. Write a "1" to this
  71                 property to arm a special "ship" mode that extends shelf life
  72                 by reducing the leakage to about 2.8 microamps. The chip will
  73                 remain in this mode (and no longer respond to I2C commands)
  74                 until some external power-supply is attached raising the input
  75                 voltage above 1V. It will then automatically revert to "0".
  76                 Writing a "0" to the property cancels the "ship" mode request.
  77                 The ship mode, when armed, activates once the input voltage
  78                 drops below 1V.
