I believe the 12v battery used to feed the 48v battery. When I leave a battery charger plugged in over night at the hood, I access workshop menu and see the 48v battery goes up in charge maxing out at around 75%.

Mind sharing what your issue is? If you don't even have Xentry/WIS I doubt you can remove the 48v battery. You have to initiate bleeding the cooling system, follow some procedures and deal with the BMS issues; that's forgetting the specific 48v charger required which only hybrid battery shops really have. Is the issue that the car's been in an accident?
