Hi, team:

   I am testing BQ34Z100 use EVM, and wants to test >5V situation, When I configure VOLTSEL bit in GUI found it couldn't be changed. Could you help check it?

    Write all Data memory when in single cell mode and then apply the voltage divider. Otherwise you may end up in a situation where the voltage reading of the gauge is below threshold to change data memory
