Feature:1. Using no photosensitive resistor light control technology, suitable for solar lawn lights, solar wall lamp and so on.2. Support lithium batteries, lithium iron phosphate batteries and so on, widely applications.3. Output with 1.1A current, automatic recovery fuse for overcurrent protection, having stable performance.4. Light control or can be set as non‑light control, the default for light control, charging during the day, the light automatically on at night.5. Circuit board is controlled by single chip microcomputer to realize small volume and multi‑function.Specification:Item Type: Solar Charge Controller BoardMaterial: Glass FiberModel: S665Application Scenario: Suitable for solar lawn lamp, solar wall lamp, solar ceramic lamp, solar energy landscape lamp, solar energy column lamp, solar garden lamp and other solar lamp products for circuit controlCompatible Battery Voltage: 3.7V-24VMaximum Charging Current < 3AMaximum Output Current < 1AControl Mode: Light control.Package List:5 x Solar Charge Controller BoardNote:1. The output of this circuit board cannot accept all types of boost circuits.2. Do not use LED lamp bead directly, need to connect the step‑down drive.3. The battery must be added with a protective plate, otherwise the battery will be damaged by overcharging or over discharging.
