In case anyone else on the forum needs a reference or good video on the RV Custom BCC (Battery Control Cabinet), these links might be of interest to you. There may be different versions of this BCC out there, but this info seems to apply to my 2013 ACE 30.1 and many other coaches and years as well. It would be valuable if there was a listing of coach model; build year; and which battery control system was used in that coach. It would help folks troubleshoot DC electrical issues or at the very least help understand how their battery charging system is connected and should work:
