Battery calibration

I have just installed the PX4 flightstack on to a Pixhawk and am trying to do a battery calibration. How does one calculate what to enter into the Bat_C_Scaling and Bat_V_Scaling? For the Pixhawk, which scaling do I use? FMU or PX4IO?

You have 4096 ticks for 3.3V ADC input voltage. That should give you all you need to calculate the total scaling from current to ticks.

Sorry, could you elaborate more? I’m afraid I don’t quite understand.

sir ,
am using 3 sell battery so write on 3sells .
full voltage per cell how much i give = ?
empty voltage per cell how much i give =?
voltage divider ---------------- calculate. how to calculate please explain in detail
amp per volt ------------------ calculate . how to calculate please explain in detail
