Powering ESP8266 & ESP32-CAM with 3 18650s and solar panel

[finnmeow]

I’m working on a project where I need to power both ESP8266 (has NodeMCU Base Ver 1, accepts 6V-24V via barrel jack) and ESP32-CAM (has a built-in AMS1117 regulator) using a 3x 18650 battery pack(solar powered). I have the following components for power management:

TP4056 (with protection) – 5V 1A Charging Module
XL6009 – Boost Converter
HCW-P715 – Buck Converter

1. How should I wire these components together to safely distribute power without destroying my project?
2. Can I directly connect the battery pack to a terminal block and split power between the TP4056, XL6009, and HCW-P715?
3. Is there a better alternative for everything in powering both MCU? (must be solar powered and uses 3 18650s)

I know just enough to know this is a mine field. I also know the right answers are on the forum. Just do some searching and look at many hits, as there are many wrong answers.

How much current does the completed project consume when its active and not active and how many mA hours per day do you need ?

Why 3x18650?

The components chosen are not at all appropriate for a solar charging setup. This charger module is.
