reminder:
1. Check the battery! The battery has peeling or leakage, rust, or deformation. Please stop using this battery.
2. Use a multimeter to test the battery voltage. If the battery voltage is lower than 3V, please stop using it. These belong to over discharged batteries, which are not fully charged, discharge quickly, and cannot charge the phone
3. If the battery is below 3.5V, there may be no output, and it needs to be fully charged to ensure the power output. If a certain battery has severe heat generation, please remove it. If the heat generation is severe, it indicates that the internal resistance of the battery is too high, which has affected its use.
4. Distinguish the positive and negative poles and install the battery. Please try to use a battery with good consistency for DIY. Reverse installation will burn the board and there is no boost output. Please be careful when doing household chores.
5. After rechecking the battery and ensuring there are no issues with the use of the nesting material, proceed with the cover installation and DIY is completed perfectly.
