Product Description
Currently, lithium batteries are becoming more and more popular. Especially on solar energy storage systems and UPS (Uninterruptible Power Supply) Lithium ion HV system, etc. For the lithium iron phosphate battery cells, the single cell voltage is nominal rated 3.2V, all voltage, current, power (kW) and energy (kwh) applications are based on this. High voltage lithium battery system usually refers to the battery system voltage is greater than or equal to 96V, for example, 192V 50Ah battery system is 1P60S (60 cells series connected) cell connection based on 50Ah single cell capacity, 240V 50Ah battery is 1P75S cell connection, 384V 100Ah battery is 1P120S cell connection based on 100Ah cell, etc. We also can parallel cell first for double or triple total capacity. The corresponding battery capacity is usually 50Ah, 100Ah, 150Ah, 200Ah, etc.

Standard Charge
At (25±2)℃, the cell is charged by a constant current of 0.5C (A) to the cut-off voltage 3.65V, then kept at this voltage until the current is less than 0.05C (A).
| No. | Item | Requirements | Measuring Procedure |
|
|
|
|
After standard charged, the cell undergo a rest for 1h, then is discharged by current 0.5C(A),1.0C(A) respectively to cut-off voltage 2.5V. This test is allowed to be repeated for 3 times if the discharge capacity fails to meet the technical requirements. |
|
|
|
|
A) After standard charged, the cell undergo a rest for 5h at (55±2 )℃, then is discharged by current 1.0C(A) to cut-off voltage 2.5V; |
|
|
|
|
After standard charged,the cell undergo a rest for 28 days, then is discharged by current 1.0C(A) to cut-off voltage 2.5V. The discharge capacity is capacity retention. After standard charged again,the cell undergo 30min’s rest , then is discharged by current 1.0C(A) to cut-off voltage 2.5V. The discharge capacity is capacity recovery. |

|
|
At (25±2)℃, 300kgf clamp force: the cell is charged by current 1.0C (A) to 3.65V, then kept at this voltage until the current is less than 0.05 C(A), followed by 30min rest, subsequently the cell is discharged by current 1.0C (A) to 2.5V . Cycle continues until the capacity decays to 80% of the nominal capacity |

Transportation
The cells should be packed into boxes under the charge of 30% ~ 50%SOC. During the transportation, they should be protected from severe vibration, shock , extrusion, sun or rain.
Storage
Cells should be stored (more than 1 month) indoor with a dry and clean environment at
0 ℃~35 ℃, and charged and discharged every 6 months. Keep the last charge under 30%～ 50%SOC.
Attentions
1, It is necessary to ensure that the voltage, current and temperature of the cell are monitored and protected when the cell is charged and discharged.
2, Please keep the cell away from heat source, fire source , strong acid, strong alkali and other corrosive environment.
3, Do not short connect or install the battery with incorrect polarity at any time.
4, Do not mix up with cells from different models or manufacturers.
5, Do not use external force to make the cell fall, impact, puncture, do not disassemble the cell or change the external structure.
6, Please keep the cell’s charge under 30% ~ 50%SOC, and avoid direct sunlight or high temperature and humidity environment when the battery is not used for a long time,
7, Please wear protective devices such as rubber gloves when operating the battery.
8, Please immediately stop using if there have leakage, smoking or damage with cell , and contact our company to deal with.
