Victron LiFePO4 Battery 25.6V/200Ah Smart-A - BAT524120610LiFePO4 Battery 25. 6V 200Ah Smart A Why lithium iron phosphate? 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 Size and weight Saves up to 70% in space Saves up to 70% in weight Expensive LFP batteries are
