Instructions for use:
1. after powering up, the blue indicator of the module is always on and the red indicator flashes slightly;
2. when the battery is fully charged, the module's red and blue indicators are always on.
Tips:
1. the wiring must be distinguished between positive and negative polarity, reverse connection burn IC
2. use short and thick wires for charging, if they are too thin and too long, the connection resistance will be high and the battery voltage will drop more after charging
3. the connection wire should have good contact, otherwise the battery voltage will drop more after charging
4. the output current can be adjusted by changing the fixed resistor in the circuit board to change the output current from 100mA to 1000mA
5. if the 5V input voltage is high, such as 5.2V or 5.5V, it will cause the charging current to be less than 1000mA, which is normal. This is normal. The high voltage makes the chip hot and will automatically reduce the charging current to reduce the chance of the chip being burned.
6. the charging current is too high, or in a high temperature environment, need to do heat dissipation treatment
7. the ammeter for testing the current can only be connected in series to the 5V input of the charging board
8. the satisfactory effect of the charging current should be 0.37 times the capacity of the battery. For example, a 1000mAH battery charging current of 400mA is fine
9. the faster the charging speed, the worse the charging effect, the more the battery voltage drops after charging is completed
