I have connected a PM to the APM 2.6 and have done a perfect V & A calibration exactly as stated in the wiki. I do not have wireless telemetry so can only see this when stationary and connected via USB.
1. The battery %'age is always 99%. Does this only show the %age under load or am I doing something wrong?
2. Secondly, the CurTot shows 2500 after a flight however when I charge it puts 3000mAh back in. This is after a perfect calibration of V & A. What could be going wrong? (I do have some LED's connected where the current does not go through the Power module.. But i highly doubt the LED's are pulling 500mAh!!)

I connected a watt meter and ran a full throttle test while connected to the ground station.
Wattmeter:
Amps: 28.4
mAH: 336
Volts: 10.4
APM Ground Station:
Amps: 28.0
mAH: 328
Volts: 9.3
I have done the Current Calibration at over 10A and the Voltage Calibration. Why is the voltage so far off under load? This cause the Voltage Failsafe to kick in Prematurely. Do I need to calibrate voltage at load?
The graph below shows the readings (But not the WattMeter Readings)
