  • Cylindrical battery cells

    Powering Every Possibility

    LiFePO₄ batteries are widely used in electric vehicles, solar energy storage, medical equipment, and industrial machinery due to their high thermal stability, long cycle life (≥2000 cycles), and superior safety profile compared to other lithium-ion chemistries.
  • Solar-powered telecom station

    Smarter Energy for Modern Applications

    LiFePO₄ cells offer consistent voltage discharge curves and minimal self-discharge (<3%/month), making them ideal for standby systems, UPS, telecom towers, and advanced electronics such as drones and electric mobility devices.

    Empowering Renewable Energy

    LiFePO₄ batteries are a key enabler in renewable integration, with
  • What is the difference between lead-acid batteries and iron phosphate batteries?

    LiFePO₄ batteries offer significantly longer cycle life (2,000–5,000 cycles) compared to lead-acid (300–500 cycles). They are lighter in weight, charge faster, and maintain a more stable voltage throughout discharge. LiFePO₄ also has superior thermal and chemical stability, reducing fire or explosion risks. Although lead-acid batteries are cheaper upfront, LiFePO₄ provides lower total cost of ownership over time due to longevity and efficiency.

  • Is parallel or series connection freely possible?

    LiFePO₄ batteries can be connected in parallel or series, but only when the voltage (V) and state of charge (SOC) of each cell are the same to ensure stable operation. If the SOC or voltages do not match, a critical current imbalance may occur, which may result in cell damage or BMS triggering due to overcurrent. In particular, the presence of a cell balancing circuit is important when connecting in series, and each cell must be synchronized to a full state before connecting in parallel. Connecting without prior balancing may result in reduced lifespan, overheating, and in severe cases, fire hazard.

  • Can I use any battery charger?

    LiFePO₄ batteries require a dedicated charger, and chargers for general lithium-ion or lead-acid batteries have different voltage profiles, which can cause overcharge or undercharge. LiFePO₄ batteries typically require a constant voltage charge of 3.65V per cell, and a CC/CV (constant current/constant voltage) charging method should be applied accordingly. The most stable and efficient charging can be expected when the charger output current is within 0.2 to 0.5 C of the battery capacity. An unsuitable charger can lead to cell damage, performance degradation, BMS trigger, or safety accidents.

  • How can I use lithium iron phosphate batteries safely for a long time?

    Keep charge voltage below 3.65V and discharge voltage above 2.5V per cell to protect battery health. Always use a BMS to prevent overcharge, over-discharge, and short circuits. Operate within -20–45°C, and store at ~50% SOC in a cool place for long-term storage. Periodic capacity tests and cell balancing are essential to maintain long-term performance.

  • How is the Charging Time of a LiFePO₄ Battery Calculated?

    Charging time depends on the battery’s capacity (Ah) and the charger’s output current (A). For instance, charging a 100Ah battery with a 10A charger would take approximately 10 hours, as it delivers 10Ah per hour. However, actual charging time may vary depending on BMS configuration, ambient temperature, and initial State of Charge (SOC).

  • How Long Does a LiFePO₄ Battery Last?

    Lithium Iron Phosphate (LiFePO₄) batteries typically support 2,000 to 5,000+ charge-discharge cycles, translating to 5 to 10 years or more under daily use. Avoiding high temperatures, overcharging, and deep discharges helps extend lifespan. Battery quality, BMS protection, and environmental conditions also significantly affect longevity.
