This can fill 15 pieces of 18650 power li-ion batteries,But this is only a shell, there is no battery inside. Preparation before assembly: (1). If a new core is used, please note: a. 18650 power lithium battery core must be selected, b. A group of 5/10 cores must be equipped with resistance and capacitance to make their voltage the same. (2). If the old battery is repaired, please test the voltage at both ends of each cell. If the voltage is different, please charge each cell to the same voltage value. Very important: Ensure that the voltage of each cell is the same before welding PCB. Package include: as the following picture:no battery cell Kindly Reminder (Very Important!!! ): 1. There are no batteries in the package !!!!!! 2. If you need batteries, please don't place orders ! 3. If you don't have the knowledge of battery assembly, please don't place an order !
