    This will typically be caused by supply current in the top cell sensing path. To avoid this, the supply pin should have its own filtering elements, not shared with the top cell sense input. This is done correctly on the demo board, so if the demoboard is doing this then it may be that the CELL12 connection is not tied to the top cell potential.
