What are the advantages of 18650 lithium battery with and without protection board?

The protective plate is suitable for all people to use and has over-discharge protection: when the battery is about to run out, the voltage reaches a lower value required, the protective plate will also be closed and cannot be discharged, so the product will automatically shut down, forming a Kind of over-discharge protection purpose. Overcharge protection: When charging the product, when the voltage reaches the higher voltage (4.2V) of the battery, the protection board will automatically cut off and close, indicating that it is full and no longer charging. The formation of an overshoot protection purpose. Short-circuit protection: When the battery is accidentally short-circuited, the protection board will be automatically closed within a few milliseconds and will not be energized. At this time, the positive and negative poles will be fine when they touch one piece. The formed short-circuit protection will not cause an explosion. Over-current protection: When the battery is discharged, the protection board will have a larger current limit. Different products are different. When the discharge exceeds this current, the protection board will automatically close the 18650 lithium battery without the protection board. The size of the 18650 lithium battery is larger than that of the protection. The battery of the board should be short, and some devices cannot use the battery with a protective board due to the initial design. Without the protection board, the cost is low, and the price is relatively cheaper. Lithium battery without protection board is suitable for use with relevant experience, generally do not overdischarge and overcharge, the service life is similar to that with protection board.
