Hi Gabriel,
How are the cells being connected to the board - are they connecting in a certain order? This thread may be helpful which describes a similar issue: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/755199/bq76940-voltage-adc-shock-and-sometime-damage
