AEM Battery Management System Satellite (MUST BE USED WITH MASTER - 18 Cell Taps)
The VCU communicates with the BMS via the Master Module and all battery packs need at least one Master unit. The Satellite Modules are connected to their Master via a high-speed serial interface (isoSPI) that allows additional units to be daisy chained together, adding as many Satellites as necessary for the battery pack configuration.
