The feature of the LiFePO4 batteries:

1, Safe: The iron-lithium battery is more safe and reliable than the lead acid one. It does not explode or burn when bump, heavy stress, needle pricking, short circuit, overcharge and overheat.

2,Environment-friendly: Accredited with ROHS, with out any hazardous and noxious substances.

3, Small in volume and light in weight: The iron-lithium battery is about 1/2 the volume and 1/3 the weight of the lead-acid battery.

4, Powerful: able to discharge with 20C at 65.C max.

5, Steady performance: high power output,1C continuous,3C pulse for normal cells and 20 C for special design. low self-discharge rate, less than3%monthly.

6, Long cycle life: over 2000 cycles with capacity staying at 80% min.

7, Lower average price per year: the average price per year is 100 Yuan RMB less than the lead-acid battery for 5 years.

8, No memory effect: always ready for charge and use, with no need to charge after a full discharg.

9, Wide temperature range: Available for use when the temperature ranges from 20°C to 70°C .
