Electrical ratings are a rabbit hole of nuance and stipulations and are never as simple as a single amp/power/voltage value. None of it is helped by the BS electrical ratings used in RC where ratings are not standardized and the manufacturers never explain how they arrive at their ratings.

At the end of the day, ratings are there as guidelines to prevent you from melting equipment. You'll be perfectly fine if you use a motor that is within the ESC's guidelines and an appropriately sized battery (and by that I mean a hardcase 4s lipo meant for 1/8 vehicles if you're using a 1/8 motor/esc and not a small airplane soft shell 4s pack with 16awg leads). Trying to use RC ratings for much else is a fool's errand.
