EVE 3.2V LiFePO4 batteries (105Ah-314Ah) are lithium iron phosphate cells optimized for solar, EV, and backup power systems. They offer high energy density, 4,000+ cycle life, and thermal stability, making them safer and longer-lasting than traditional lithium-ion batteries. Their modular design enables scalable 48V configurations for industrial and residential energy storage needs.

How Do EVE LiFePO4 Batteries Compare to Other Lithium-Ion Technologies?
EVE LiFePO4 batteries outperform conventional lithium-ion in safety and longevity. Unlike NMC batteries, LiFePO4 chemistry resists thermal runaway, operates efficiently in -20°C to 60°C ranges, and retains 80% capacity after 3,000 cycles. Their 3.2V nominal voltage provides stable discharge curves, minimizing voltage sag in high-demand applications like EV powertrains.
Recent third-party testing revealed EVE cells maintain 92% capacity retention after 2,000 cycles at 1C discharge rates, compared to 78% for standard NMC cells. Their oxygen-immobilized cathode structure prevents combustion even when punctured, a critical advantage confirmed by independent UL 9540A fire safety tests. For cold climate performance, EVE’s electrolyte additives enable 85% capacity delivery at -20°C versus 45% for conventional lithium-ion chemistries. This makes them ideal for off-grid solar installations in northern latitudes where temperature extremes are common.
