For selection the number of cell of battery in 220vdc system there is two ways one way consider 108 cells another way consider 110 cells; which one is preferred?

It is related to acceptable minimum and maximum system voltage, end-voltage of each cell which specified by manufacturer regarding rated capacity (Ah) of cells (e.g. C8=200 AH, in 8 hour continues discharge time) and permissible maximum cell voltage. The standard end-of-discharge voltage used for lead-acid cells is 1.75 volts per cell (Vpc) in North America. In other parts of the world, 1.80 or 1.81 Vpc is frequently used. These end voltages typically apply to cells rated at discharge rates equal to or greater than 1 h. The use of these end voltages ensures that the potential for damaging a lead-acid battery due to overdischarge (i.e., caused by overexpansion of the cell
