Hi!
Im currently trying to power my esp32 dev board from my 18650 Lithium battery.
This is my current setup:
18650 -> BMS -> Mini Booster Step Up converter DCDC 3,7V -> 5V -> esp32 VIN.
The problem im facing:
Im only getting 2,7V output from my BMS. This leads to the DCDC Stepup to not being able to provide 5V which means the esp32 is not powered. My guess is that the load is too small for the BMS to detect.
Could someone tell me what the proper way to power my esp32 from my battery is?
Here are the exact components I am using:
links are in german, sorry :(

Note:
i have also tried with an TP4056 instead of the bms mentioned above but since they are almost the same if had the same effect.
Thanks in advance, I really appreciate if someone takes his/her time to help me out <3
