    • Nominal Capacity: 4000mAh , Real
    • Nominal Voltage: 3.2v 3.3v
    • Battery Dimension: 26.5x71mm(0.02mm)
    • Battery Weight: About 93g
    • Internal Resistance: less than 20 mohms
    • Cycle life: More than 2000 times, DOD at 80%
    • Input Charging Voltage: 3.65v/cell
    • Input Charging Current: 2A
    • Continuous Discharging Current: 3C
    • Max Current Discharge: 5C
    • Discharge cut-off Voltage: 2.50v/cell
    • Charging Temperature: 0C ~ 45C
    • Discharging temperature: -20C ~ 60C
    • Storage temperature: -20C ~ 45C




    A LiFePO4 in 26650 size with fairly good capacity.










    The two cells matches very nicely and can deliver the rated 3C or 12A.























    Conclusion

    This is a good LiFePO4 battery and as usual for this type it has very stable output voltage and less energy contents than the more common LiIon types, but longer life.



    Notes and links

    The batteries was supplied by a reader for review.

    Nice, 30 A must be brutal for any cells.
    can lifepo4 charged quickly if charger can deliver more than 1A constant current (as per tests), any damage it can cause in this case?
