LiFePO4 battery characteristics:

1. Extremely safe and stable chemistry:

Rigid Aluminum alloy housing protection, and BMS built inside to balance protect the battery.

2. Long life-cycle:

5-7years/2000 times cyclelife

3. Lighter and smaller:

1/2 weight of SLA batteries. 70% size/weight of NiMH/NiCd batteries

4. Wide operating temperature:

High temperature resistance(-20-60 degrees celsius)

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. No memory effects and highly efficient charge:

It can be recharged anytime, no reduction of the capacity

7. Green product:

Environment friendly: Clean and Green energy poses no pollution on our enviroment

With balance BMS and charger
1/3 weight of SLA battery
