A lithium ferrous phosphate (LFP) battery is a type of lithium-ion battery known for its added safety features, high energy density, and extended life span. The LFP batteries found in EcoFlow’s portable power station are quickly becoming the leading choice in off-grid solar systems.

LiFePO4 first found widespread commercial use in the 1990s. Since then, prices have dropped enough for the average consumer to use the technology in most of their battery-powered devices. LFPs are less prone to fires and thermal runaway when compared to Li-ion batteries. Unlike lithium-ion, Lithium ferrous phosphate batteries are also free of unethically sourced nickel and cobalt, making it the go-to choice for many energy storage applications.
