This UPS is so versatile that we can use it for many other things than WeatherDuino.
The second down converter is because I'm using this unit as UPS for a 5V device.
The RGB Led isn't necessary, maybe a LED isn't necessary at all, I connected it in a way which is GREEN when there is mains power, and RED when power is provided by the UPS batteries. Not a recommendable thing, as the LED helps to draw the batteries.
In true, the RED Led is always ON, but with a very low bright, while the GREEN is a lot brighter, so, when there is mains power, what you see is the GREEN. Just an easy (but bad) way to achieve a goal.

Werk,
very clever idea, can you please advise where you bought the rocker switch as I cannot find any with those dimensions and I have printed the case

File works perfectly now, thank you. 

Very impressive work! I have had my 3D printer for over a year now but haven't had the courage to try designing anything of my own to print. Thanks to that link, I'll now have to be brave and try....
