The minimum voltage needed to power the UXBMs is 7 volts. The power leads must be connected
across the proper amount of cells or monoblocs to achieve this while considering the lowest level
reached during a discharge. For example, if 2 volt cells are being monitored, then the power leads must
be connected across at least five cells. This is considering an end voltage of 1.65V per cell and would
reach a value of 8.25V at end of discharge.
The following is an example connection for a 2V scenario on a 241 cell count string.
