With an FSO based system you could do this easily with help of oevents.

In the file /etc/freesmartphone/oevents/rules.yaml exists two entries

for actions to be taken when the battery is nearly empty. You could

easily edit these entries and do LED actions or play some sound files.

The relevant entries are these:
    while: PowerStatus()

    filters: HasAttr(status, "critical")

    actions: SetLed("gta02_power_orange", "blink")
    trigger: PowerStatus()

    filters: HasAttr(status, "empty")

    actions: Command('poweroff')
You can add your own actions as described at the beginning of this file.

For example the following line look good for your scenario:
# - PlaySound(file)         : Action that starts to play an audio file
I already edited this file to start the red AUX LED blinking when on

battery to see if my freerunner is in standby or just the screen is

blanked. And i also edited the maximum brightness to be 60 and not 90 in

this file to save some energy (bright enough to still see everything

good). So you can do really nice things with help of the oevents rules. :)
Ciao,
