    5.3 Standard Charge and Discharge
    5.3.1 Standard Charge
    Lithium ion battery charging method: Constant Current / Constant Voltage (CC/CV)
    Standard charge current: 0.2C5A =1400mA
    Charge voltage: 16.8V
    Use 0.2C5A constant current to charge batteries, convert to use 16.80V constant voltage to charge when the batteries voltage achieves 16.8V at 23±3℃. Cut off charging when the charging current decline to 0.01C5A
    5.3.2 Standard Discharge
    Standard discharge current: 0.2C5A =1400mA
    Batteries should be discharged with constant current 0.2C5A to 12.00V at23±3℃.
