Q128C 500W vs Q128C 800W vs Q128SXC

[flangefrog]

Anyone know the differences between these motors? On BMSbattery the Q128SXC is listed as a 135mm front motor (although it says it supports cassette?) but on AliExpress the Q128SXC is shown as a 135mm rear cassette motor that looks identical to the Q128C. I'm not sure what the difference would be between Q128 500W and 800W? I haven't got any response on these questions from BMSbattery.

I'm sure you've seen typos on the web before. Especially on English language Chinese run websites.

Given that they have identical weight and outside dimensions, my bet is on there being no differences. Except for marketing purposes.
