1Pcs Night Light Led Lamp Control Switch Battery Charger Charging Controller Module Automatic Solar Panel Battery Charger Board

Description: Automatic Solar Panel Battery Charger Board Night Light LED Lamp Control Switch Battery Charger Charging Controller Module Functional parameters: 1. Charging during the day, automatically turning on the lights at night, and automatically turning off the lights at dawn 2. Remove resistor r5, no output when not connected to the photovoltaic panel, no switch required, convenient for storage and transportation 3. Anti backflow, constant current LED driver output, short circuit, overcharge and over discharge protection Prevent over discharge voltage of 2.9V, restore voltage of 3V, prevent over charge of 4.25V, restore charge of 4.1V 4. Control output by detecting whether the solar panel generates electricity, without the need for photosensitive components 5. Only applicable to 5-7V solar panels, 5V panels cannot exceed 10W, and 6 or 7V panels cannot exceed 18W 6. If the open circuit voltage of the solar panel is lower than 5V, it may not charge, and if it is higher than 8V, it may damage the controller 7. Choose 2V or 3V LED wick with working current bigger than 600mA/1000m The 3.7V lamp board can be directly used in terms of power, with a maximum output current of 600/1000mA for driving 8. It is recommended to use solar panels with a current 5-10 times the calculated capacity for battery capacity Specifications: Material: Plastic+Metal Size: 39 * 26mm Packing: 1pcs Note: 1.
