Battery Power #5

Hi,

What are the battery specs this board needs on the charge port

Reason I ask is that if you powered by a 3.7V lipo, which at fully charged is measured at 4.2v, the 5v input comes out at 3.7V

When the lipo reaches 3.7v the 5V is now 3.4 volts and the 3.3 is even lower, then the esp32 stops working with lots of capacity left in the battery..

Any ideas ?

3.7V lipo

The module does not have a boost circuit, only regulator to convert USB/5V and battery inputs to 3.3V. So the only way to get 5V is to get 5V from USB, which is then connected to 5V pins.

P.S. this issue should be closed.
