$begingroup$ So in other words, as the cell in the parallel bank approaches total charge depletion, it would not affect the bank V when it is 100% depleted,but it would eventually cause that bank to be depleted sooner than the other banks in the battery. When the charge of that bank is depleted, it will output less V & cause the battery to have a lower V
