Each as3525 target should probably define its own battery properties

(dangerous/shutoff battery level, discharge/charge curves) in a file
|
|

called powermgmt-<target>.c in its own sub-directory.
|
|
||||||

For now, this file provides simple uncalibrated settings to get at least
|

a basic reading for all as3525 targets with a lithium battery.
