Hi, I have powered my ESP32s with batteries before, but I have so far always used 5V through the 5V input pin. I now purchased a WiFi Kit V3, and wanted to power it with a 3.7V Li-Ion battery. I have a feeling that I am being quite dumb, and missing something obvious, but for some reason, the ESP32 did not power up from the battery. I connected it to the JST1.25 header on the bottom of the board. Can someone help me understand what I am doing wrong?
