Difference between Polymer Lithium Core and Polymer Lithium Battery

The battery consists of the core and the shield,

Battery removal panel is the core.

The protection plate, as its name implies, is used to protect the core. The main role of the protection plate is:

1, overcharge protection: When you charge, the voltage reaches the battery's maximum voltage(4.2 V), the protection plate will automatically shut off and can not be charged.

2, over protection: When your battery power is running out(the phone is about 3.6 V) the protection plate will also close, can not discharge. Your device will shut down automatically.

3, over current protection: When the battery is discharged(used), the protection plate will have a maximum limit current(different instrument requirements are not the same), and when the discharge exceeds this current protection plate will automatically close.

Short circuit protection: When your battery is accidentally short-circuited, the protection plate will automatically close within a few milliseconds and will not be energized. At this time, it is okay to hit the positive and negative poles.
