Working Principle

The LiPo Rechargeable Battery stores electrical energy through reversible electrochemical reactions occurring between the positive and negative electrodes separated by a lithium-ion conducting polymer electrolyte.

During charging, lithium ions move from the positive electrode to the negative electrode, where they are stored. During discharge, the lithium ions move back to the positive electrode while releasing electrical energy that powers the connected electronic device.

The battery provides a nominal output voltage of 3.7V, with the voltage gradually decreasing during discharge. It should always be charged using a dedicated LiPo battery charger that provides proper charging control and protection to maximize battery life and ensure safe operation.
