Esp32 model-s power issue

Using Arduino General Electronics
1

i am using this esp32 board - ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller.

i am having a problem in my project i am powering my components using 5v pin like 4 components because they cannot work on 3.3 v
i am using 5v pin to power the components and power the esp32 also but when i am using lithium ion battery which is 4.2v and powering it, it is not starting and powering but when i am powering esp32 with a usb cable then it is powering on and working fine also with normal board temperature

please resolve this issue

Most Lithium batteries are 3.7 or 3.8 volts. The 4.2 value is when it is being charged. Is you battery being charged when you are having this issue?

yeah you are right my battery is charged 3.99 v not 4.2 v but still its not powering the esp32 and my battery is not at charging while having the issue

Does the datasheet for your development board say that it will work on less than 5V?

I moved your topic to a more appropriate forum category @divyansh823.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.

The nominal voltage of the 18650 battery is 3.7V. Might not be enough to power your system.

Big-board dual core ESP32 could have a larger voltage regulator, that needs at least 4.3volt supply to provide 3.3volt to the processor. Small board ESP32, like the Seeed ESP-32-C3, with a smaller LDO regulator, are a much better choice for a single LiPo cell. The Seeed C3 has battery solder pads and a built-in charger.
