1. ### V6 Product Description This product is a component without a battery cell. It is used for repairing and assembling battery packs and is only suitable for personnel who are familiar with battery performance and have practical experience in battery assembly. 2. #### Assembly Preparation - **When using new battery cells**: - Please use 18650 power lithium - ion batteries with low internal resistance. The models and parameters should be the same. Do not use energy - storage lithium batteries. - Please test the voltage of each single battery cell and charge the single battery cells to make the voltage of each cell the same. The cell voltage should be higher than 4.1V. - **When repairing old batteries**: Please test the voltage across each battery cell. If the voltages are different, charge each battery cell to the same voltage value. 3. #### Very Important Precautions When soldering the PCB board, the voltage of each 18650 battery cell must be the same. The cell voltage should be higher than 4.1V. 4. #### Product Information - **Color**: Black - **Material**: Plastic 5. #### Packaging Contents One set of battery box with a protection circuit board.
