usage method:

• Input voltage can be input through the USB or IN+, IN- , IN+ voltage positive, IN- negative electrode.
• D1 is full of electric light, green LED
• OUT+, OUT- connected to the load, the interface does not support charging and discharging over current protection.
• VBAT+, VBAT- lithium battery charging, VBAT+ connect the positive electrode of the lithium battery, VBAT- connect the anode of the lithium battery. When charging the red LED D2 light up, green LED D1 goes out. Positive and negative can not be reversed.
• The best charging current is 0.37 times of the battery capacity, for example, the battery capacity is 1000mAH, the charging current is 400mA
