Lithium batteries Lithium Battery LFP 200Ah 25.6V Smart Victron Energy Photovoltaic Storage System Victron Energy BAT524120410 €4,677.75 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.
