For a power station with a nominal voltage of 24 volts, if using LiFePO4 cells with a nominal voltage of 3.2 volts, you''d need 8 cells in series (24 volts / 3.2 volts per cell). In contrast, using NMC cells requires just 7 cells in series to be considered a 24V battery. This is due to its higher 3.6 volt nominal voltage.
