Quick breakdown into key components
The background electronics are a clever blend of three requisite circuits, that is to say, a lithium-ion battery charger circuitry, a battery protection circuitry, and a dc-dc boost converter circuitry. Refer to the annotated image provided below (and the table next to it) to get a deep insight on the underlying electronics.
