The lithium iron phosphate battery is generally considered the safest of all lithium-iron battery types. Because of the solid electrolyte and the cell chemistry LiFePO4 cells are considered to be intrinsically safe. A built-in self-monitoring function detects any deviation within the battery.

Why to choose for our “LiFePO4” = Lithium Iron Phosphate batteries

  • High performance
  • Extremely safe & stable chemistry : 
    It is non-explosive & will not catch fire under collision due to overcharging or from short circuit.
  • High discharge rate capability :
    When accelarating, the battery will have better powerful performance than other Lithium and NiMh batteries.
  • Long service life :
    Over 6-7 years, up to 2000 cycles (under 80%DOD)
  • Rapid charging ability :
    The battery can be charged quickly & safely to 85% within half an hour & can stand high discharge rate.
  • Deep Depth of Discharge (DOD) :
    The batteries can be fully (100%) discharged.
  • Lead-acid batteries can oly be discharged till 80%, otherwise they will be damaged. So with the same capacity the LiFePO4 battery is more powerful.
  • High & stable Voltage :
    The voltage is better than the Lead-acid (2V/cell), NiMh & NiCd (1.2V/cell).
  • The voltage of LiFePo4 is 3.2V/cell also the voltage will remain from 3.2V – 2.85V within 85% of its discharge time.
  • No memory effect
  • Environmentally friendly :
    Non-toxic, non-contaminating, no rare metals.
  • CE, UL and SGS/ROHS approved.
  • Wide working temperature :
    Extremely cold & hot weather will not affect the performance of the battery (from -25°C to +70°C)
