    2. Smart Lithium battery 12V 50Ah Electrical Characteristics & Test Condition

        @Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.

     

    NO Items Criterion Condition
    1 Internal Impedance ≤20mΩ Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument.
    2 Capacity ≥49Ah Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 180 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.

    Cycle life (DOD%100)

    ≥2000cycle Discharge with the current of 0.5C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
