If the lithium battery has a protective plate, it can be charged directly with a USB cable. The function of the lithium battery protection board is to prevent the lithium battery from being overcharged and overdischarged. When the battery voltage reaches 4.2V, the protection board will cut off the current input.
If the lithium battery does not have a protective plate, it cannot be directly charged with a USB cable. The charge cut-off voltage of the lithium battery is 4.2V. That is to say, when the internal voltage of the battery rises to 4.2V, the charging should be stopped, otherwise the lithium battery cells will be damaged. The voltage output through the USB cable is generally 5V, which is higher than the cut-off voltage of the lithium battery. Therefore, if the battery does not have a protective plate, it will cause the battery to be overcharged.
