First attempt - wiring diagram

[Slimpreaper]

Hi guys,
This is my first attempt at buikding a GBZ.
I've used tinkerboys v2.1 board, gearbest screen & gearbest power module as the basis for the build.
I've pieced together the wiring diagram.
Can you please have a look and let me know if ive got it right?
For now i have not wired in the switch.

Thanks so much for your help!

at first glance most things seem ok......

but i wouldn't put a switch on the + positive of the battery, this will hinder you from charging the unit when the power/switch is OFF....

put the switch on the + positive of the power out from the generic power module (if it goes to a PCB board or power strip)

Ah ok, good idea, perfect sense, i will do this.
I havent actually wired in the switch yet so ill pop it in where you suggested once I get it.
Thanks for your help!

So I've got all this wired up now (minus switch) it is directly connected for now.
But I cant initiate boot up from battery.
If i plug power directly into the pi0w then it boots up.
I've tested for voltage rightbtheough from battery to pi0w and there is voltage at all points.

Does it have to be 5v at pi? Im only getting 1.9v
Am I missing something? Do i need the switch?

I just resoldered a few connections and retested the voltages.

Referencing the above sketch

C - 3.8V
A - 4.8V

3.6V at top of tinkerboy

3.6v at t pi0W. This too low to run isnt it?
