Does anyone have experience running ESP32 projects with rechargeable batteries. I see packs that have 4.7V – is that enough? How about 6V – too much? How about higher voltages with an inexpensive stepdown dc-dc board to deliver 5.0V? Can the Vin pin supply the power to the board? The board does have a voltage regulator. What does that regulator do?

If you’re using an ESP32 Development board, you should be able to power it with 6V (in the Vin pin), because it has on-board voltage regulator. Using only 4.7 V in the Vin is not not enough…
The on-board voltage regulator lowers any input voltage to 3.3V (in order to power the ESP32 correctly)…
