Solar Generator Charge Controller Auto Light Control circuit Switch Lithium Battery Charging Board

Wiring method: 1.B+B- connected lithium battery 2. S+ S- connect to solar panel 3. L+L- output Wiring sequence: 1: Connect the lithium battery, the battery must have the corresponding protection board 2: Connect to the LED, the lithium battery has power and the LED lights up 3: Connect to the solar panel. At this time, the solar panel is illuminated with light, and the LED is off, and the LED is on without light. The switch can be installed if it needs to be turned off at night or the switch interface has been reserved compatible with transportation and storage. Precautions: 1: The stable working output current of the control board cannot be greater than 600ma, otherwise it may cause output protection 2: Charging and anti-backflow without overcharge and overdischarge protection Lithium batteries must be used with corresponding protection boards (mobile phone batteries all have 3.7v protection, and more than 18650 do not have them. 3.7v protection boards cannot be used in series) 3: Pay attention to waterproofing and insulation 4: LED lamps cannot use boost drive 5: 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
