3. Electrical Characteristics & Test Condition


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


No. Items Standards Testing Methods


Internal Impedance

Impedance ≤20mΩ Under 20±5℃ Environment Temperature , the Usage Frequency of Fully Charge( 1KHz) , Use AC Internal Impedance test machine to test
2 Nominal Capacity 125Ah Rest for 0.5~1 hour after fully charge, Using electrical loader to connect with the battery output port, and discharge with constant current 0.2C till it can’t discharge. Do the cycle three times, if there is one time that the discharge time is equal or more than 285minute , you can stop.
3 Short circuit protection No load ability after short-circuit .comeback capability of loading after remove the lead away,


Short the pack with the lead (<50mΩ). If remove the lead away, connect the electronic loader with P+,P- of protection board again, so load ability comes back.

4 Allowed Maximum continuous charge Current 60A charging with 15A for more than 0.5h and the added temperature of battery pack less than 15℃.
5 Allowed Maximum continuous discharge Curren 60A Discharging with 15A for more than 0.5h and the added temperature of battery pack less than 15℃.
6 Over Current Protection 50A~70A Using electron load connect with output side, discharge with 50A for about 2sec Discharge with 70A for less than 20 millisecond.
7 the delay time of over current protection 5.0-20.0ms Using electron load connect with output side, discharge with more than 70A and record the voltage wave of output side with oscillograph . Numerating the time of voltage from wave to zero for voltage
8 cycle life Discharge Capacity ≥80% Discharge it with the current of 1C to the cut-off voltage, and store it for 15min.Charge a battery with the current of 1C, then keep the voltage and current constant and continue to charge it until completed . After storing the battery for 15min. The test is to be conducted as per the above cycles. The cycle should be 2000 times. At the 2001 times discharge capacity should not be less than ≥80% with 0.2C.
10 Charge Retention remain capacity≥90% At 20±5℃ completely charge and store it for 28days,and then discharge it with 0.2Cto the cut-off voltage. (We suggest charge the battery every three months)
11 Over Discharge Protection furbish Charging With0.2C Charge the battery with 0.2C for 5min and measure the output voltage (≥25V)of the battery pack. The battery should have load .
12 Discharge Temperature Characteristics The ratio between discharge capacity and charge capacity should be not less than the following value At 20±5℃ discharge the battery with the current of0.2C to the cut-off voltage and record charge capacity. Store the battery at the following temperature for 2h and discharge the battery with 0.2Cto the cut-off voltage.
    Discharge Current Discharge Temperature
  -20℃ 0℃ 25℃ 55℃
    0.2C 60% 0.8 1 0.95



4. Storage and Transportation


1) Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
2) Battery should be stayed in the ware house -20℃~35℃ where it’s dry, clean, shade, and well-ventilated.
3) The battery should be stored in 50% SOC during transportation.
4) The battery need to be charged every 6 months if out of use
5) Keep the battery against dropping, turning over and serious stacking during loading.
