Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. 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 lead-acid battery will fail prematurely due to sulfation if it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged). Or if it is left partially charged or worse, fully discharged (yacht or mobile home during wintertime).
A LiFePO4 battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of LiFePO4 compared to lead-acid.
Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency. LiFePO4 is therefore the chemistry of choice for very demanding applications.
