Battery damage free replacement. 2. These are battery parts components (excluding battery), battery assembly experience can be directly assembled battery, or battery damage can replace the damaged battery parts 3. This product is No battery core assembly, it is used to repair and assemble the battery pack, only for people who are familiar with battery performance and have experience in battery assembly. 4. When assembling the battery cells to pay attention to safety, if you use 18650 power lithium cells must be selected, a set of 5/10 cells must be matched with resistors and capacitors to make the voltage consistent. All cells should have the same voltage, internal resistance and capacity as much as possible. 5. Be sure to pay attention to safety when assembling the battery. If using a new core, 21700 power lithium batteries must be equipped with resistors and capacitors to make the same voltage. If the old battery has been repaired, charge each battery to the same voltage value.
