Overcharge, overdischarge, and large charge and discharge currents for External Battery Pack,18650 Lithium Cells
Overcharge of the battery is avoided. Any overcharge of the lithium-ion battery will lead to serious damage to the battery performance and even explosion.
Avoid deep discharge below 2V or 2.5v, as this will quickly and permanently damage the lithium-ion battery. Internal metal plating may occur, which can cause a short circuit, making the battery unusable or unsafe.
