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)
