I am using a firebeetle 2 esp32 and I have added a lipo battery to the on-board connector provided. In the readme file it says about connecting 18650 battery with a resistance to the analog input. In the case of LiPo battery this does not work properly. Should I connect the positive of the battery directly to the analog input pin omitting the resistance?
Where does it say that and for what purpose? That shouldn’t be a thing unless maybe for measuring battery voltage.
18650 / Li-Po is the same in pretty much every regard.
I show this wiring schematic and I got a bit confused:
In my case should I just add a jumper connector from the + of my battery to A0? Could it be that the firebeetle 2 ESP32 has already a port directly connected to the + of the battery plug and I should set that port to the battery usermod setting?
I checked the corresponding user manual but I don’t see such a direct connection

Seeing the schematic the Firebeetle 2 has built-in battery monitoring connected to A2 with a 1:2 divider.
