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)
