High Capacity LiFePO4 26650 3.2V 3800mAh Battery Cells for UPS Ebike AGV RV
Discharge capacity at normal temperature: After full charge, the experiment can be put on hold for 10 minutes; 0.2c discharge to 2.5V allows five repetitions. When the range of three consecutive experiment can be completed ahead of time and the maximum value of the test results can be obtained.
Discharge performance at different temperatures: After standard charging of normal batteries, it should be stored at least 12 hours in the constant temperature environment of -20℃,-10℃,0℃,10℃ and 25℃, respectively, and 5 hours of 60℃. Then discharge with 0.5C current to the corresponding termination voltage. When the ambient temperature is more than 15℃, the termination voltage is 2.5V, if less than 15℃, which is 2.0V.
