Why LiFePO4 Battery?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.Performance and Stability---Much higher instantaneous power output than conventional batteries. These battery life-cycles are about 5 years in normal operationCost-Effective ---Much cost-effective comparing with conventional battery in terms of costs of expensive controller system and professional maintenance tasks.
