AEM Battery Management System Master - Universal
AEM's Battery Management System Master Module is the control hub for EV and hybrid battery pack monitoring, built for teams running custom battery builds in race, prototype, and conversion projects. It's the brain that talks to the VCU and keeps every cell in check.
This listing covers the AEM BMS Master Module, SKU 30-8401M, suited to any battery pack configuration. Every pack needs at least one Master unit, and capability is expanded by adding Satellite Modules (sold separately) as your cell count grows.
Note: This is the Master Module only. Satellite Modules are required to expand monitoring beyond the Master's base capacity and connect via isoSPI daisy chain.
Key Features
- Communicates directly with the VCU to manage the battery pack
- Each Satellite Module adds 18 cells and 3 thermistors of monitoring capacity
- High speed isoSPI serial interface links Master and Satellite units
- Satellites can be daisy chained to suit any pack size
- Scalable architecture for custom EV and hybrid builds
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your battery pack configuration and required Satellite count before ordering.
