Hello TI Community,
I have a Question. I develop a BMS for 10 LiIon Cells. My circuit diagram is finished. But how can I check at the first, initial start which cell gets balanced? Can I connect paralell to the 47 ohm resistors a Led (R2 - R12)?

A high impedance sensor would be preferred to a direct LED which could alter the current flow in the filter. If you look at the differential voltage across the filter capacitors, the balancing cell will have a low average voltage, the adjacent cells will have a higher average voltage and the un-related cells will typically look normal.
