The JFBMS_Slave is a smart battery management system (BMS) slave module designed for direct integration into CAN bus–based power systems. It connects straight to your ESC or BMS master with zero additional wiring harnesses or protocol converters — just plug into the CAN bus and go.
Built for flexibility, the JFBMs_Slave supports 3S to 32S cell configurations, making it suitable for everything from compact hobby builds to high-voltage industrial and electric vehicle packs.
Key Features
Direct CAN Bus Integration
Communicates natively over CAN bus with your ESC or BMS master. No UART adapters, no signal converters — a true plug-and-play topology that keeps your wiring clean and your data reliable.
3S–32S Cell Support
Monitor and balance anywhere from 3 to 32 series-connected cells on a single board, covering a wide range of battery chemistries and voltage classes.
Splittable PCB Design
Need a smaller footprint? The JFBMS_Slave can be split in half, giving you a compact module supporting up to 16S per half. Perfect for tight enclosures, slim battery packs, or distributed mounting inside a frame or housing.
Real-Time Cell Telemetry
Provides per-cell voltage monitoring and pack-level data back to the master BMS or ESC over CAN bus, enabling real-time protection, balancing decisions, and state-of-charge estimation at the system level.
Scalable Master/Slave Architecture
Deploy up to 8 JFBMS_Slave modules on the same CAN bus to scale your system. That means up to 256S total when fully expanded. The master coordinates — the slaves report. Simple, modular, and massively expandable.
