Versatile Charging: Works with multiple battery types (3.2V, 3.7V, 4V, 11.1V and 12V) and suitable for a range of small solar-powered LED lighting products. _x000D_ 2. Automatic Lighting Control: Turns on automatically at night and off during the day, offering hands-free energy savings. _x000D_ 3. Voltage Output Matches Battery Voltage: The output matches the battery's voltage, ensuring optimal performance and longevity. This product automatically adjusts its output to match the battery's voltage, ensuring maximum efficiency and minimizing wear and tear on the battery. _x000D_ 4. Non-Photovoltaic Detection Circuit: Controlled by detecting changes in solar panel-generated voltage, eliminating the need for expensive photoelectric devices. _x000D_ 5. Wide Range of Applications: Suitable for lawn lights, landscape lights, courtyard lights, stairs lights, DIY lights, path lights, and decorative lights. _x000D_ _x000D_ _x000D_ Specification: _x000D_ Origin: Mainland China _x000D_ Color: Green _x000D_ Quantity: 1/5/10pcs (optional) _x000D_ Material: PCB _x000D_ Size: About 31x18mm/1.22x0.71inch _x000D_ Weight: 5g _x000D_ Kind reminder: _x000D_ The battery voltage must match the voltage and power of the solar panel _x000D_ The working voltage and power of the LED output terminal must correspond to the battery voltage _x000D_ Wiring method: _x000D_ 1. B+B_ Connected to lithium battery _x000D_ 2. S+S - Connected to solar panels _x000D_ 3. L+L-connected output _x000D_ Preventive measures: _x000D_ 1. The stable working output current of the control board should not exceed 600ma, otherwise it may cause output protection _x000D_ 2. Lithium batteries must be equipped with corresponding protection plates to prevent charging backflow and no overcharging or discharging protection. (Mobile phone batteries have 3.7V protection, but 18650 and above do not. 3.7V protection plates cannot be used in series) _x000D_ 3. Pay attention to waterproofing and insulation _x000D_ 4. LED lamps cannot use boost drive _x000D_ 5. The battery voltage of the controller is the output voltage, which is infinitely limited by current and voltage. 2V3V LED beads cannot be directly used and need to be driven by a step-down constant current or series current limiting resistor. The output current is the maximum working current, not a constant current _x000D_ Special reminder: _x000D_ 1. The output power is the actual power, please confirm the actual power consumption of the load before use _x000D_ 2. Directly connecting to a 3Vled may damage the controller or LED _x000D_ 3. The battery must be equipped with a protective plate, and the battery voltage must match the open circuit voltage of the solar panel _x000D_ _x000D_ _x000D_ Note: _x000D_ 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.
