I have the below in /etc/rc.local (so that whenever I tweak the
values because I want to, say, charge up to 100% before a flight,
they will be back to normal on the next restart at the latest):

modprobe tp_smapi
echo 30 > /sys/devices/platform/smapi/BAT0/start_charge_thresh
echo 80 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

We don=E2=80=99t think of ourselves as being perfectionists, really. To us
it=E2=80=99s more about desperately trying to have it sound more or less OK.
