Specification:
Origin: Mainland China
Type: Module
Condition: New
1. Charge during the day, turn on the light automatically at night, turn off the light automatically at dawn, the output voltage is the output voltage when there is no voltage from the battery.
2. The circuit controls the output by detecting the voltage change generated by the solar panel, no need for photosensitive components; suitable for all kinds of batteries.
3. Product size: 30.00×11.00×4.00mm/1.17*0.43*0.16in
Wiring Method:
1. B+B- connect to lithium battery
2. S+ S- connect to solar panel
3. L+L- output
Wiring Order:
1: Connect the lithium battery, the battery must have the corresponding protection plate
2: Connect the LED, the lithium battery is powered LED light
3: Connect the solar panel. At this time, the solar panel has light, LED off, no light LED on.
If it needs to be turned off at night or the switch interface SW is reserved for transportation and storage, a switch can be installed.
Precautions:
1: Control board stable working output current can not be greater than 600ma, otherwise it may cause output protection
2: Charging anti-return current, no overcharge and overdischarge protection lithium batteries must use the appropriate protection board (cell phone batteries have 3.7v protection, 18650 and above do not. 3.7v protection boards can not be used in series)
3: Pay attention to waterproof, insulation
4: LED lights can not use boost drive
5: Controller battery voltage for the output voltage, current limiting voltage, 2V3V LED lamp beads can not be used directly, need to step down constant current or series current limiting resistor drive, the output current is the maximum operating current, not constant current!
Special Tips:
1: The output power is the actual power, please confirm the actual power consumption of the load before use.
2: Direct access to the 3V led may damage the controller or LEDs
3: The battery must be equipped with a protection plate, the battery voltage must be matched with the open-circuit voltage of the solar panel.

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
