C&D Technologies MBC-1971-1 Printed Circuit Board

C&D Technologies MBC-1971-1 is a printed circuit board (PCB) from C&D Batteries, cataloged as a Reactor Balance Board and described in distributor listings as a PLC/Add-On Board with the exact part number MBC-1971-1. The component is sold and listed by several vendors as a genuine C&D PCB, reinforcing its role as an on-board circuit module intended to be integrated with C&D power/battery system assemblies as an additional control function. In public catalogs, it is identified specifically as MBC-1971-1 PCB, with some listings using wording like “Reactor Balance Board” to describe its purpose within the MBC family of circuit boards. Availability appears through secondary market channels, with listings that emphasize the part number and board-type description rather than generic specifications. Buyers should verify the exact model number (MBC-1971-1) against their equipment’s documentation to ensure compatibility, as this board is a specialized module rather than a universal, stand-alone PCB. This succinct identification—C&D Technologies, MBC-1971-1, PCB, Reactor Balance Board—helps buyers confirm they are sourcing the correct add-on for legacy C&D battery-system configurations.
