5. Note:
1)。 The ammeter can only be connected to the 5V input port of the module.
2）。 The charging current should preferably be 37% of the battery capacity. For example, the charging current of a 1000mAH battery should be 400.
3）。 The connecting wire should not be too thick.
4）。 Ensure that the connection points are in good condition.
5）。 If the input voltage is too high, such as 5.2V or even 5.5V, the charging current will be less than 1000mA, which is normal. When the voltage is too high, the chip will automatically reduce the charging current to protect the chip from burning. In addition, when the operating temperature of the chip is around 60 ° C, it is normal for the chip to feel hot.
