You don't mention any requirements - battery life etc.

First thought - this comes to mind.

Thank you!
Your suggestion is an ESP board with built-in battery holder an charger.
I would prefer a separate box for the 5 Volt.

In which case you need to give much more information about your exact requirements.

But as an ESP32 is 3.3V (after it's regulator) a Li-Ion 18650 or pack makes a sensible option.

now I changed my thoughts.

In my project is also a motor driver board connected to a 7.4V 6000mAh LiPo battery.

Now my question changed:

What is a safe connection from the LiPo battery to the 5 Volt pin?
Is a diode and than a tantal condensator enough to lessen high frequency disturbances ?

Bother the little bit higher voltage the USB source of the PC?
