5V 1A Micro USB Interface 18650 Lithium Battery Charging Board Charger Controller Module Protection Dual Function Charge Control Buy 2 pieces to enjoy an extra 3% discount Product parameter: 1. Input voltage: DC4.5V-5.5V; IN+ IN- pad wiring or MicroUSB 5V input; 2. Full charge voltage: DC4.2V; 3. Charging current: 1A adjustable; 4. With charging indicator; 5. Working temperature: -10℃~+85℃; Instructions for use: 1. After power on, the blue indicator light of the module is always on, and the red indicator light flashes slightly; 2. When the battery is fully charged, the red and blue indicator lights of the module are always on; Tip: 1. Wiring needs to distinguish between positive and negative poles, and reverse connection to burn IC; 2. Charging needs to be connected with a short and thick wire. If it is too thin or too long, the connection resistance will be large. After the charging is completed, the battery voltage will drop more; 3. Connect the wires with good contact, otherwise the battery voltage will drop more after the charging is completed; 4. The output current can be adjusted by itself, changing the fixed resistance in the circuit board can change the output current of 100mA~1000mA; 5. If the 5V input voltage is too high, such as 5.2V or 5.5V, the charging current will be less than 1000mA, which is normal. When the voltage is high, the chip generates heat, which will automatically reduce the charging current and reduce the probability of the chip being burned; 6. If the charging current is too large, or it is used in a high temperature environment, heat dissipation is required; 7. The ammeter for testing current can only be connected in series to the 5V input terminal of the charging board; 8. The satisfactory effect of charging current should be 0.37 times of battery capacity. For example, a 1000mAH battery charging current of 400mA is sufficient; 9. If the charging speed is fast, the charging effect will be poor. After the charging is completed, the battery voltage will drop more;
