Jrifedptry 10PCS SD1512TA Solar Controller Charging Street Light Switch Circuit Board Lithium Battery Charg Board 2A Easy to Use

Charging in the daytime, automatically turning on the lights at night, and automatically turning off the lights at dawn, the output voltage is the output voltage when the battery has no voltage. The circuit controls the output by detecting the change of the voltage generated by the solar panel, without the need for photosensitive elements; it is suitable for a variety of batteries. The battery voltage of the controller is the output voltage, unlimited current and voltage limiting, 2V3V LED lamp beads cannot be used directly, it needs to be driven by a step-down constant current or a series current limiting resistor, and the output current is the maximum working current, not constant current
