Great job nick-tech!
On K5 the easiest way to get battery info is:
Code:
[root@kindle root]# gasgauge-info
usage:
gasgauge-info [-chklms] [-i <seconds>] <registers...>
-h help
--help help
-i s interval (seconds)
-c output state of charge in percent
-s same as -c
-v output battery voltage value
-l output battery charge current (load)
-k output battery temperature
-m output battery available capacity (mAh)
