Occkic Automatic Solar Panel Battery Charger Board Night Light LED Lamp Control Switch Garden Street light 3.7V 7.4V 11.1V Module

Wiring:

1: Connect the lithium battery

The battery must have a corresponding voltage protection board

2: Access LED

At this time, the LED is on (if it is not on, you can short T+T- to test)

3: Connect to the solar panel. At this time, the solar panel is illuminated with light, and the LED is turned off without light illumination.



Precautions:

1: The stable working output current of the control board cannot be greater than 3A, 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 18650 batteries do not have 3.7v protection plates and 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.

3.2v LED lamp beads outside the battery cannot be used directly. It needs to be driven by a step-down constant current or a series current limiting resistor.

(Example: 1wLED lamp beads work requirements are 3v260ma, using 3.7v lithium battery, need to step-down drive or string more than 5 ohms power resistor to limit current)


Notice! LEDs cannot be driven by boost

If the light does not light when the solar panel is not connected to facilitate transportation or storage, you can remove the resistor r5 or manual switch

3.7v lithium battery can only use 5-7v solar panel maximum 30w lithium battery must have 3.7v protection plate

LED maximum output power 10w

7.4v lithium battery pack can only use 10-14v solar panel maximum 30w lithium battery must have 2 strings of special protection boards

LED maximum output power 20w

11.1v lithium battery pack can only use 18-22v solar panel with a maximum of 40w Lithium battery must be equipped with 3 strings of special protection boards LED maximum output power 40w
