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
