The difference between 18650 batteries with and without protective plates.

The difference between 18650 batteries with and without protective plates.

Equipped with a protective board suitable for all groups of people, it has over discharge protection: when the battery is about to run out of power and the voltage reaches a lower required value, the protective board will also turn off, and the product will automatically shut down, forming an over discharge protection purpose. Overcharge protection: When charging the product, if the voltage reaches a higher voltage (4.2V) of the battery, the protection board will automatically power off and turn off, indicating that it is fully charged and no longer charging.

A form of overshoot protection. Short circuit protection: When the battery accidentally short circuits, the protection board will automatically close within a few milliseconds and will not be powered on again. At this time, even if the positive and negative poles touch each other, it will not cause an explosion event. Overcurrent protection: When the battery is discharged, the protection board will have a larger current limit, which is different for different products. When the discharge exceeds this current limit, the protection board will automatically shut down.
