Banebots RS775-12 and 775-18

[Grim Tuesday]

I was browsing the motor curves again and came upon an issue that has always puzzled me. As far as I know, we are only allowed to provide motors with 12v of power. However, there is always a Banebots RS775-12 and Banebots RS775-18 listed. Maybe I just completely don't understand it but which motor is attached to the PG71 and PG188 gearboxes sold by Andymark? Is it a RS775-18 being run at 12 v? I ask this because I'm looking to compare the PG71's operated by 775 series motors and AM 9015 ones and unfortunately Andymark has no data on the 9015 ones.
