you need to be in the kernel-power-settings
usr/share/kernel-power-settings.
i find the easiest way with filebox and when i'm in this dir i press the tools icon and 'open terminal here'

then i type leafpad (profile you want to change)
this opens leafpad and lets you edit the profile don't forget to save

i can't see changing the max having any problems with batterypatch function
hope this helps.

to everyone
i've installed power v48 so i'm going to check battery life with it and batterypatch.
