The nominal voltage of a LFP cell is 3. 2V (lead acid: 2V cell). A 12. 8V LFP battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series. A LFP battery does not need to be fully charged. Service life even slightly improves in case of partial charge
