The length of the cable from your batterie(s) is missing on your pictures.

This is from the manual i found on their website (translated from german):

. cable length to your motor should be 10cm
. The length to the batterie should never exceed 20cm
-> Exception: Schulze 18.97KWF (max 30cm)

If your cable length do exceed those values, then you must add low ESR capacitors to the ESC.

Hope this helps.
