I don't trust that eBay seller one bit, they have conflicting information between the product description and details.... I believe they are misleading you into thinking that it came from an Axial, but they are just listing compatibility.
I went to Axial's website and did a generic search for...
There's no doubt in my mind that the HW ESC comes from the same OEM as the "rebranded" version, however I seriously doubt they are using the same internal components.
Ever since COVID, I have noticed that quality from HobbyWing has been reduced and I can only imagine how much worse the quality...
First off, that ebay link is not a HobbyWing branded ESC, it's a clone with no guarantee that the parts quality will be as good as what you would get from a HobbyWing certified label.

the SC8 is gross overkill... in fact many racers prefer Max10 SCT for 4S with a 4268-2000KV motor so it won't break a sweat on 2S
*** EDIT ***
I just saw you mention 80A which is the NOT the SCT ESC, there is a Max 10 G2 which is limited to 3S...
