You cannot change the 'low-power' event thresholds right now. The code
checks if the AC adapter is on and all batteries are in low or critical
state. The problem is that the firmwares use different thresholds for
low/critical, so you cannot use a common value (like 5%) as you suggested.

If you want to be informed about this, you could set a 'critical-capacity'
limit in /etc/envsys.conf to be notified... but note that this event won't
check all batteries and ac adapter state and you'd have to check this
in the script yourself...
