Why Choose TBA-M16S BMU
High Precision
±10mV voltage & ±2°C temperature – critical for accurate SoC/SoH estimation.
Isolated & Safe
Galvanic isolation on communication paths ensures reliability in high‑voltage systems.
Scalable Architecture
Daisy‑chain SPI bus allows dozens of BMUs to monitor hundreds of cells.
Seamless Integration with HV Battery Stacks
The TBA-M16S is a fundamental building block for modular battery management systems. Each BMU monitors 16 cells and 7 temperature points. Multiple units can be connected via daisy‑chain SPI to form a complete high‑voltage battery pack (e.g., 200‑800V). The isolated CAN interface communicates directly with the main BMS controller, enabling real‑time protection, balancing commands, and fault diagnostics.
Compatible with LiFePO₄, NMC, LTO cells. Works with industry‑standard main BMS platforms.
