Cycle Life

• Temperature: 77-86  F(25-30 C); Charge, 1C CC to 29.4V, and CV to 200mA cut off; Discharge, 1C DC discharge to 21.2V, 80% or more of 1st cycle capacity at 1C discharge of operation, cycles quantity must not less than 2,000 cycles.
• Remarks: Rest 10 min. after charge and discharge
• Standard Charge: Charging the cell initially with constant current at 1C and then with constant voltage at 29.4V (accuracy +(or minus) 0.05V) until charging current declines to 1C at 77-86  F(25-30C)
• Standard Discharge: Discharging the cell with constant current at 1C till cut-off voltage at 21.2V. Temperature: 77-86  F (25-30C)
• Initial Internal Impedance: This means AC impedance of the pack measured at 1KHz after half fully charged. Initial Internal Impedance < (or equal)10m(ohm)
•  Initial Capacity: The capacity means the discharge capacity of the battery, which is measured with discharge current of 1C with 21.2V cut-off voltage after the standard charge.
• Initial Capacity: @95% normal capacity. Temperature: 7 -86  F(25-30  C).
• Charge Choice
  • Standard charger: 29.4V/80A
  • Charging mode: CC/CV
  • CC: charging current <(or equal) 80A
  • CV: constant voltage 29.4V
  • Charging cut off condition <(or equal) 200mA
