Advantages of LiFePO4 battery
1.Long cycle life:5000times cycles,100% DOD after 1200 times 80% capacity remain.
2.Small size and light weight:LiFePO4 battery size and weight is 1/3 of Lead acid battery
3.<1% low self-consuming rate
4.LiFePO4 battery price is 2.5 times of lead acid battery
5.With advanced BMS,like CANBUS,SMBUS,RS485,RS232,UART,communication system.
6.Built-in automatic protection for over-charge, over discharge, over current and over temperature control.
7.Can be charged using most standard lead-acid charges.
8.Green eneygy to potect our world better.
