LiFePO4 Cells

LiFePO4 (Lithium Iron Phosphate) batteries are a type of lithium-based rechargeable cell known for long cycle life, stable chemistry, and consistent performance. These batteries are widely used in energy storage systems, solar applications, battery packs, and other applications requiring durability and reliability.

Compared to standard lithium-ion cells, LiFePO4 batteries operate at a lower nominal voltage and are designed for applications where safety, longevity, and thermal stability are important considerations.

LiFePO4 Battery Specifications

Nominal Voltage: 3.2V – 3.3V
Fully Charged Voltage: 3.6V – 3.65V
Discharge Cutoff Voltage: Typically 2.0V – 2.5V
Cycle Life: Often 2000+ cycles depending on usage conditions
Capacity & Discharge Rates: Vary by model and format

Common Applications for LiFePO4 Batteries

✔ Energy Storage Systems – Used in solar storage and backup power applications
✔ Battery Packs & Modular Systems – Integrated into custom and commercial battery solutions
✔ Marine & RV Power Systems – Suitable for deep-cycle applications
✔ Industrial Equipment – Used in systems requiring long service life and stability
✔ Portable Power Solutions – Used in power stations and off-grid setups

LiFePO4 vs Standard Lithium-Ion Batteries

LiFePO4 batteries differ from standard lithium-ion cells in both voltage and chemistry. They offer longer cycle life and increased thermal stability, but operate at a lower nominal voltage and typically lower energy density.

Devices and systems must be specifically designed to support LiFePO4 batteries, including proper charging profiles and voltage ranges.
