DFRobot 2x18650 Lithium Battery Shield 5V 2A / 3.3V

This 18650 Lithium Battery Shield features 5x 5V/2A and 5x 3.3V/1A outputs, as well as a 5V/2A USB output. The battery is charged via a 5V Micro-USB or USB-C input. The shield provides overcharge and discharge protection to extend the lifespan of your battery. A DIP switch allows you to toggle between Hold and Normal mode. In Normal mode, the device automatically turns off when the current flow is too low. In Hold mode, the output remains on until the battery is empty and the discharge protection is activated. The output can also be manually turned on and off using the button on the side. The status LEDs on the back indicate which mode you are in and whether your batteries are full or charging.

Note: The 18650 batteries are not included and must be purchased separately. The maximum current output is 3A, but this is not recommended and depends heavily on the quality of the 18650 battery. Caution: When inserting the 18650 Lithium batteries, pay attention to the polarity + and -, otherwise the charging chip will be destroyed.
