@walterleonardo please share what hardware you use for battery management and how it is connected.

I have these two prototypes. And in both I have the same issue. with the last version 0.7.0.rc1 main and develop branch

Sorry for the inconvenience. Unfortunately, web-flashed firmware and Diagrams now use different ways to measure battery levels.
In web-flasher firmware configured to use analog pin 36 with voltage divider 37k and 100k ohms
The MAX1704* circuit in the diagram is missing in the 0.7.0 release candidates.

Unfortunately, until I re-implement this chip, you will either:

1. use 0.6.0 and modify some code with PlatformIO IDE to use MAX1704* chip
2. modify hardware to use a voltage divider

I can help you with the code if you want
