I have this Arduino form li-on battery backpack - http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=50_76&products_id=318&osCsid=b74638f58ae26170577069c34698d681
Now I’ve hooked the power loop up properly and that’s working. What I’m curious about is how to go about reading the power status.
From what I’ve seen on a post about the pack:
The status pin is actually just tied directly to the lithium battery’s positive terminal. Measuring the voltage here you can estimate the life of the battery.
Those schematics need to be updated to include the 3.3v and status. I will try and post more updated ones.
The 3.3v is rated for 100mA and the 5v is rated for 500mA continuous.

However how do I go about reading this? Can I use the Domino directly or do I need some other components in-between?
