We recommend connecting the cells by spot welding. Another methods of joining can damage the cell at high temperatures.


Based on the customer's wishes, we offer the service of formatting cells and assembling cells into the required pack.


New cells are partially charged at the factory. Before first use, the cells must be charged to full capacity. The first charge must be made with a current of no more than 0.5C, and a voltage of no more than 3.65V.


Cell operation is only possible with protection circuits. Without the use of protective circuits, permanent damage to the cells is most likely to occur.
