Tesla Model S Cell Tap Board

Tesla Model S/X OEM Cell Tap Board – Original BMS PCB

This is an original Tesla cell tap board, as found inside Model S/X battery modules. Designed by Tesla for internal battery management, this printed circuit board (PCB) connects directly to each cell group within a single module to monitor voltage and temperature data.

These boards are essential for OEM-level diagnostic work, battery module restoration, or Tesla module repurposing where full factory integrity is required.
