Battery percent #864

Open GoogleCodeExporter opened 9 years ago

1.When you start the APM the Battery percent will shows 99%, although when  the 
battery Voltage is not near to 12.6V==100%

2.I found the problem at the APM Code GCS_Mavlink.pde at line 196 :
" battery_remaining = (100.0 * (g.pack_capacity - current_total1) / 
g.pack_capacity);"
This means no matter how full the battery is it will start every time with 99%

3.So my idea is to show the consumed mAh and the percent does not depend on 
consumed mAh but of the voltagelevel (I know its difficult because a lipo 
battery has no linearly discharge curve)

I hope you understand my problem and i am sorry for my english
