LiFePo4 power Battery: The new generation power solution for Electric Vehicle-----a most advanced technology in the world ---the application tendency for lithium iron phosphate as cathode (LIFEPO4 technology).

Due to the shortage of fossil fuels and environmental concerns, we re convinced that the green energy industry and related industries will become the main stream in the coming 30-50 years. This causes a strong demand of rechargeable batteries.

Lithium iron phosphate cell has the best safety characteristics, long cycle life (up to 2000 cycles) and good availability. It is very suitable for high discharge rate occasions such as EV (including e-bike, electric scooter, and electric car), power tools, UPS and solar energy system.

Key Features and Advantages of LiFePo4 media

1. High Performance

2. Extremely Safe/Stable Chemistry High intrinsic safety, no explosion & will not catch fire under collision, over charged or short circuit. High thermal stability of phases up to 500C.

3. High Rate Capability For all high power output application

4. Extraordinary Long Cycle Life Best can up to 2000 cycle life, would be over 8 times life of Lead Acid and 3 times of NIMH.

5. Environmentally Non-toxic, non-contaminating No rare metal, UL, CE, SGS/ROHS approved. LiFePo4 technology does not contain any heavy metals and does not exhibit the "memory effect" of Nickel-Cadmium and Nickel-metal Hydride solutions.

6. Another key benefit of our LiFePo4 technology is its flexibility, both in terms of battery application and cell design. Small in size and light in weight 1/3 weight of Lead Acid and 65% weight of NIMH.

7. We  provides not only LiFePo4 Battery pack, but also total solution which includes protect circuit module with balance charging function, BMS and specific charger.
