Cost Performance

♦ Long-run Cost: LiFePO4 battery could work at 60°c, with long life 5-10 years.

♦ Smaller Space: 1/3 of the lead acid battery.

♦ Low Maintenance Cost: maintenance free, centralized monitoring and module installatin also to reduce cost for transportation.

♦ Safety Cost: stable discharge platform to avoid euipmet exception.

♦ Save Electricity Power: with same capacity, LiFePO4 battery is more powerful hank lead acid battery, and could support longer.
