Why choose LiFePO4 battery instead of lead acid battery?

1. Green product

LiFePO4 material is no harm to enviroment and human being.

2. Cycle life

Over 2000 cycle times, 5-7 years life.

3. Very safe

It have the best safety and steady performance, no fire, no exploding under the condition of over-charge.

4. Light weight and smaller dimension

The dimension compares with other battery. About 1/2-2/3 weight of lead acid

5. Great capacity and more powerful, rechargeable battery

We can install many single cells in series and in parallet and it can fully discharge

6. No memory effect

It can be recharged anytime, no reduction of the capacity
