Hi dear community; İs there a porblem with this battery ? or will all batteries behave like this ? where do i wrong ? what should i do for run it with a battery ?Thanks in advance and best regards
You placed 3.7V onto an ESP32's 3.3V bus is, most likely, an issue.
Please don't come back here in a few weeks asking why your project stopped working. 4V is too high a voltage for an ESP8266. It may work for a bit, but it won't work reliably long term. Add a regulator.
Are you serious, instead of testing more, you waste our time (well, our mistake) with that?Maybe you should try to learn some basic electronics first, these are not going to get easier when you are building more complex systems.Kari
... i tried with different battery everything normal. I detected battery was faulty. Thanks for your opinion. Problem Solved
