Characteristics of lifepo4 lithium ion battery

1. Transient pulse discharge (10s) to 20C.

2. Two good high temperature properties: the external temperature is 65C and the internal temperature is up to 95C

3. When the final discharge temperature of the battery reaches 160C, the structure of the battery is safe and the battery can withstand high temperature performance.

4. Even if the battery is damaged inside or outside, the battery will not burn, will not explode, and will not endanger life safety.

5. Excellent cycle life, after 2000, the discharge capacity is still greater than 95% A, and the capacity loss is small.

6. over - discharge to zero volt, no damage;

7. Fast charging

8. Low cost

9. Environment friendly, will not produce toxic substances, environmental protection

10. Application of lithium iron phosphate battery

(lithium iron phosphate batteries are widely used because of their characteristics and production of batteries of various capacities.)

11. High efficiency output: standard flow rate is 2 ~ 5C, large current continuous discharge to 10C.
