Voltage drop during flight

Hi,

I am using a Pixhawk Cube 2.1 on a F450 quad with 2212 920KV motors and 30Amp ESCs. The battery is a 5200mAH 25C 3S Lipo connected via the power module which came with the cube to it. I configured the power module to the ProfiCNC HV power module and it showed a voltage of 12.3V instead of 12.6V shown on my multimeter but was the closest to the actual value. But that is not the major problem. During flight it gave a voltage drop of about 7V, which, according to my experience, is just too much.

Can anyone tell me the cause for such a drop? Kindly look at the log file here as well.
