Why LiFePO4 Battery?
1. Safety and Eco-Friendly--- Li-Phosphate material has much better thermo-resistance capability; does not explode under extreme conditions. It has complete Eco-Friendly chemistry vs. poisonous LeadAcid and Ni-MH.
2. Performance and Stability--- Much higher instantaneous power output than conventional batteries. These battery life-cycles are about 5 years in normal operation
3. Cost-Effective --- Much cost-effective comparing with conventional battery in terms of costs of expensive controller system and professional maintenance tasks.
4. Great Consistency--We match them before delivery
