What is the purpose of the BCM-12A-C battery charger module on the MXL, and how many batteries does it support?

The BCM-12A-C is a Battery Cutoff Module (not a charger) that automatically disconnects the system batteries if they discharge below the "Low Battery" system trouble threshold (Page 1) [1].
Its primary purpose is to prevent batteries from deep discharging during extended power outages.
The module connects between the system battery terminals and the battery set itself (Page 1) [1].
It supports standard MXL-IQ battery configurations, which typically consist of one of the following sets (Page 15, 18) [1]:
- BP-61: Four 6V, 15 AH batteries.
- BTX-1: Two 12V, 31 AH batteries.
- BTX-2: Two 12V, 55 AH batteries.
