Preparation before assembly: (1). If a new core is used please note: a. 21700 power lithium battery core must be selected It is suggested that the discharge rate should be higher than 10C. the discharge rate more than the = 10C 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.
