reading is the current battery
voltage in volts. The reading is updated once per second
and is shown in the LCD display. The shut down voltage
is also shown. Note: A fully charged battery pack
should show 4.8 volts or higher. When the battery
voltage falls below 4.4 volts, a flashing “Bat” will appear
as a warning message. This means there is 20-30
minutes run time left before the monitor will be turned
off automatically, when the battery voltage falls below
4.2 volts.
