TP4056 Output-Voltage too low when connected to Load
The battery voltage was too low because the system was pulling too little current. Which in itself wasnt the issue. When I checked the 3.3V output of the linear regulator I realized it was outputting 3.2V -3.3V which is sufficient to operate the ESP. The issue was that when a battery isn`t connected there is a parasitic AC influence from the USB port. Which expains why it worked right from the Lab-bench power supply. The issue was solved when I added two, 100uF capacitors to the 5V input and &quot;4.2V&quot; output. I hope this helps other people who are going through a similar proccess.
