2. Electrical Characteristics & Test Condition
Testing Conditions: Ambient Temperature: 25±5℃; Humidity:45%~75%.
Normal charge:Charge battery under CC(0.33C)/CV(54.8V) mode until over charge protection or the charge current reduce to 0.02C, and then rest for 1h.

NOItemsCriterionCondition
2.1Normal Capacity50AhAfter Normal charge, discharge @0.5C current to the end of discharge voltage.
2.2Internal Impedance≤50mΩ@50% SOC @1kHz AC internal resistance test instrument.
2.3Short circuit protectionAuto cutoff load when short circuitConnect the positive and negative of this battery pack through a lead with 0.1Ω resistance.
2.4Cycle life @DOD100%≥2000 cyclesAfter Normal charge,discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.

3. Operation instruction

  • Charge and discharge voltage: shall not exceed the maximum limit voltage specified in the specification
  • Charging and discharging temperature: the charging temperature of the battery must be in accordance with the temperature range specified in the specification
  • Charging sequence: charging by constant current before constant voltage. There is a danger if the battery is charged upside down.

 

Special note:

A short time of overcharging and over-discharging will not affect the use of the battery, but a long time of over-discharging or overcharging will affect the functional failure of the battery, or the battery is permanently unable to use, serious safety risks, need for a long time floating charge, please use the specification recommended floating charging mode. When the battery is not used for a long time, the self-discharge characteristics of the battery will also lead to over-discharge. In order to prevent the occurrence of over-discharge, the battery should maintain a certain amount of electricity and maintain its voltage at 50% SOC state.
