2 Nominal Capacity 80Ah 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 / Short circuit prohibited
4 Allowed Maximum continuous charge Current 40A charging with this current for more than 0.5h and the added temperature of battery pack less than 20℃.
5 Allowed Maximum continuous discharge Current 80A Discharging with this current for more than 0.5h and the added temperature of battery pack less than 20℃.
6 Over Current Protection 300~400A Using electron load connect with output side, discharge with 300A for about 2sec Discharge with 400A for less than 200 millisecond,
 
7 the delay time of over current protection 50~200ms Using electron load connect with output side, discharge with more than 400A 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 0.2C to the cut-off voltage, and store it for 15min.Charge a battery with the current of 0.2C, 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 1000 times. At the 1001 times discharge capacity should not be less than ≥80% with 0.2C.
9 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 of 0.2C to the cut-off voltage and record charge capacity. Store the battery at the following temperature for 2h and discharge the battery with 0.2C to the cut-off voltage.
Discharge Current Discharge Temperature
-20℃ 0℃ 25℃ 55℃
0.2C 60% 80% 100% 95%
10 Charge Retention remain capacity≥90% At 20±5℃ completely charge and store it for 28days,and then discharge it with 0.2C to the cut-off voltage. (We suggest charge the battery to 38.4~40.8V every three months)
11 Over Discharge Protection furbish Charging With 0.2C Charge the battery with 0.2C for 5min and measure the output voltage (≥27.6V)of the battery pack. The battery should have load .

1 Vibration Testing The appearance of battery should not leakage, break or explosion Fix a charged battery on a vibrating table, vibrate it for 90 minutes in three mutually perpendicular directions at the 0.8mm resonance. The frequency is to be varied at the rate of 1hz/min between 10 and 55 hertz.  
2 High Temperature Discharge Testing The battery should be no remarkable breakage, distortion. Discharge time should not less than 255mins Place a full charged battery under the environments of 55℃ for 2 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.  
3 Low Temperature Discharge Testing The battery should be no remarkable breakage, distortion. Discharge time should not less than 180 minute Place a full charged battery under the environments of -20℃ for 15-24 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.  
4 Constant Humidity & Temperature Testing The battery should be no remarkable breakage, distortion. Discharge time should not less than180mins Place a full charged battery under the environments of 40℃ and 90% - 95%RH for 48 hours. And keep it in the room temperature for 2 hours. Then discharge it at the current of 0.2C to the cut-off voltage.
5 High & Low Temperature Storage The battery should be no remarkable breakage, distortion. And charge/discharge normally Place a full charged battery in a oven with 55±2℃ for2 hours, then keep it under 20±5℃ for 4hrs, then place it in a oven with -20±2℃ for 2 hours, then keep for 4 hours under 20±5℃, cycle as high temperature-normal temperature-low temperature-normal temperature-high temperature for 10 times
