Feature:1. Lighting Modes: Comes with 4 kinds of lighting modes, including light off, flashing, always on and burst flashing, very practical.2. Lights Control: Enables light control and non light control. In light control, charges during the day and auto lights on at night.3. 10A High Power: The solar light controller ensures high power in changing and discharging, the current is less than or equal to 10A.4. Practical Uses: Suits perfectly for a variety of battery, can use in conjunction with lithium battery, iron lithium battery, etc.5. With MOS Tube: Solar end is equipped with reliable MOS tube, thus there is no need to connect an external anti back flow diode.6. Low Consumption: Also has micro power design, the control module has a micro power consumption to guarantee a longer battery life.Specification:Item Type: Solar Light Circuit BoardMaterial: PCBCompatible Battery Voltage: 3.2V-18VSolar Panel Input Voltage: Battery voltage x 1.5 = solar panel voltage. Output Voltage: Battery voltage = output voltage. Maximum Input Current: <10AMaximum Output Current: <10AControl Mode: Light control (After connecting the solar panel, the light does not light up during the day, but automatically light up in the dark). .Package List:1 x Solar Light Circuit Board1 x User ManualNote:1. The output terminal of the circuit board cannot be connected with various types of boost circuit;2. Do not use LED lamp beads directly, but it needs to be connected with a buck driver (or suitable resistance current limit in series); 3. The battery must be equipped with a protective plate, otherwise it will be damaged due to overcharge or discharge; 4. Please connect the battery first, then connect the battery to the LED bulb, and finally the solar panel.
