3.2v 6ah 48v Bms Lithium Battery Pack

3.2v 6ah 48v Bms Lithium Ion Battery Pack Electrochemical Performance:
Initial Capacity:Cell shall be charged per 3.2 and discharged per 3.3 within 1h after full charge. cycle:Under standard test conditions, the cell is first charged to 3.65 V with a constant current of 1I 1 , and then charged to less than 0.05 I 1 with a constant voltage of 3.65 V, and set aside for 30min. The cell is discharged to 2.5 V with a constant current of 1I 1 , set aside for 30min, and then carry out the next cycle for 2000 consecutive times. work condition cycle:1/3I 1 discharge for 23 seconds, then 1/3I 1 discharge for 8 seconds, then 1/3I 1 charge for 23 seconds, then 0.1I 1 discharge for 26 seconds, until soc 20% , set aside for 30min.Repeat the above steps until the discharge capacity value ≤90% the initial capacity. Low Temperature Performance:Cell shall be charged per 3.2 and stored in a temperature-controlled environment for 4h. Then discharge according to 3.3. Room Temperature Storage Test:Cell shall be charged per 3.2, then stored at 25 °C ±2 °C for 28 days. Finally discharged cell at 0.5 I 1 to ending voltage. High Temperature Storage Test:Cell shall be charged per 3.2, then stored at 55 °C ±2 °C for 7 days. After standing for 5h，discharged cell per 3.3.
