No-Original, Brand New,No Battery Cell This product is componentwithout battery core. It is used to repair and batteries pack, people who are familiar with battery performance and have practical experience in battery assembly. it can fill 3 pieces of 18650 -ion batteries, but this is only a shell, there is no battery inside. For 10.8V 12V -ion Battery dcb125 dcb127 Preparation assembly: 1. If a new core is used, note: (1). use 18650 power lithium battery andsmall internal resistance, same model and same parameters, Do not use ordinary lithium battery for energy storage (2). test the voltage of a single ,and charge the single battery so thatthe voltage of each is the same. 2. If the old battery is repaired, test the voltage at both ends of each cell. If the voltage is different, charge each cell to the same voltage value. Very important: that the voltage of each 18650 cell is the same welding PCB.
