Battery Advantages
1,Safety: 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, Environmental Protection: Accredited with RoHS, without 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.
 4, Strong Power: 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 than 3% 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 discharge.
 9, Wide Temperature Range: Available for use when the temperature ranges from -20° C to 70° C
10, Intelligent Charge System: Voltage of each cell can be detected. Each cell can be protected against overcharge, overvoltage, short circuit and overheat, and so that battery can be charged balance. The capacity of readout power volume: Each battery has 5LED lights to readout the capacity of the battery
