V_CELL1=4.4V,
V_CELL2= V_CELL3= V_CELL4=3.5V
V_CELL2=4.4V,
V_CELL1= V_CELL3= V_CELL4=3.5V
V_CELL3=4.4V,
V_CELL1= V_CELL2= V_CELL4=3.5V
V_CELL4=4.4V,
V_CELL1= V_CELL2= V_CELL3=3.5V
Note: V_CELL means the battery cell voltage. Therefore,
V_CELL1 = V_CC – V_C1
V_CELL2 = V_C1 – V_C2
V_CELL3 = V_C2 – V_C3
V_CELL4 = V_C3
