Improvment charge percent visualization: The percent display is now clipped to 100.0%. As small deviation may happen between physical battery and the theoretical counter value, percent > 100 may happen. To avoid confusion values > 100% are no longer displayed. In addition a small % has been added to the visualization of the value.
