Sometimes salvaging components from other devices is much more rewarding than just buying them. I was looking for a couple of very small batteries for a project of mine and that was the initiation of this video.
Even if you know what we have inside a cheap Bluetooth earbud, the practical design engineers may find it interesting because I dubbed into a few Power Path Management ICs in this video.
You may find them fascinating because they can do power management for Li batteries as well as can supply regulated voltage from the source or the battery or from both if the load requires more power.

Hopefully, everyone will enjoy it.
