2)LiFePo4 Battery Advantages

a)Safety:No fire,no explosion with stable chemical stucture.

b)High Energy Density

c)Low Self-Discharage:Less than 3% per month

d)Wide Range Temperature Adaptablity -20-65℃

e)Long Life Cycles:1C more than 2000

f)High Power Output

g)Environment Friendly

h)Cost Performance —LiFePO4 Battery will help you to reduce the cost!

Long-run Cost: LiFePO4 Battery could work at 60℃,  with Long Life 5-10 years

Smaller Space: 1/3 of the Lead Acid Battery

Low Maintenance Cost: Maintenance free, Centralized monitoring and module installation also to reduce cost for transportation

Safety Cost: stable discharge platform to avoid equipment exception

Save Electricity Power: with same capacity, LiFePO4 Battery is more powerful than Lead Acid Battery and could support longer.
