18650 Battery Charge Shield Board

The 18650 Lithium Battery Shield is a portable power bank that supports two voltage outputs of 3V/1A and 5V/2.2AI .

The rated current of the 5V voltage output is 2 2A, and the maximum current is 3A (not recommended for overload, easy to damage the module, and speed up the service life), the current output depends on the quality of the 18650 battery!

MICRO USB charging current 600mA-800mA.

Toggle the switch to NORMAL, and if the current output is lower than 30mA, it stops for about 10 seconds before entering standby mode.

Toggle it to HOLD; it will stay on no matter the condition until the battery dies (the 2512 resistor on the back heats up).

Special attention

The installation of the battery must determine the positive and negative poles, and the positive and negatiye poles have been clearly marked on the board! The wrong installation will burn the module!
