A 12.8V LiFePO4 battery contains 4 cells in series, and a 25.6V LiFePO4 battery contains 8 cells in series.

This is because a single LiFePO4 cell has a nominal voltage of 3.2V,

so to reach the higher battery voltages, the cells are connected in series to sum their individual voltages. 

 

A 22.2V Li-ion battery pack contains six cells connected in series, a configuration known as “6S”. This is because

each individual Li-ion cell has a nominal voltage of approximately 3.7V,

and when six of these are placed in series, their voltages add up to the total nominal voltage of 22.2V (6 cells × 3.7V/cell = 22.2V)
