Lithium iron phosphate modules, each 700 Ah, 3.25 V. Two modules are wired in parallel to create a single 3.25 V 1400 Ah battery pack with a capacity of 4.55 kWh. Volumetric energy density = 220 Wh / L (790 kJ/L) Gravimetric energy density > 90 Wh/kg (> 320 J/g). Up to 160 Wh/kg (580 J/g).
Lithium Iron Phosphate (LiFePO4) battery cells are quickly becoming the go-to choice for energy storage across a wide range of industries.
What is the difference between lithium iron phosphate (LiFePO4) and lead-acid battery?
In comparison, the lithium iron phosphate (LiFePO4) cell is a non-aqueous system, having 3.2V as its nominal voltage during discharge. Its specific capacity is more than 145Ah/kg. Therefore, the gravimetric energy density of LiFePO4 battery is 130Wh/kg, four times higher than that of Lead-acid battery, 35Wh/kg.
Lithium Iron phosphate batteries are safer than Lithium-ion cells, and are available in a range of cell sizes between 5 and 100 AH with much longer cycle life than conventional batteries. Battery chargers for LiFePO4 packs from PowerStream. 1-cell to 8-Cell chargers.
