12V20Ah polymer lithium battery pack

Features:

a. Extremely safe and stable chemistry: PCB and/or BMS built inside to balance protect the battery.

b. Long life-cycle: Can be circularly used, best can up to 2000 times recycles, 8 times of Lead acid battery.

c. Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.

d. Good performance at high temperature and high temperature resistance

e. Low self-discharge rate, less than 3% monthly.

f. No memory effects and highly efficient charge.

g. Environment friendly: Clean and Green energy poses no pollution on our environment.

Compare with other suppliers, our batteries:

1. Long cycle life: After 2000 times charge and discharge, the capacity remain 80% of the original one.

2. High energy transformation rate is up to 95%.

3. Temperature extension: In the scope of -20~70the batteries can be normally used.

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

5. Lower average price per year: The average price per year is less than the lead-acid battery for 5 years.

6. 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.

7. Green battery to protect environment: The lead-acid battery will pollute the environment seriously because of frequent replace, but the iron-lithium battery is green power without pollution.

8. Patented and beautiful appearance: The appearance designed by patent can be integrated with the hole bike.
