Extra USB and Battery Backup - abarrow - 2018-01-08 Just saw this on Banggood. It might be helpful for those who are looking for battery backup and a few extra powered USB ports. https://www.banggood.com/USB2_0-Output-Ports-Electronic-Components-Pi-Supply-USB-HUB-Expansion-Board-For-Raspberry-Pi-p-1247168.html?currency=USD&utm_source=facebook&utm_medium=cpc_elc&utm_content=zia&utm_campaign=ar-dpt-rm-nr18-value&utm_ho=18&cur_warehouse=CN RE: Extra USB and Battery Backup - Didier B - 2018-01-09 Looks good !

RE: Extra USB and Battery Backup - abarrow - 2018-01-09 Just reading up on this - they don't recommend charging the battery while the PI is running, and they don't provide a signal if the battery is running low, so out of the box it wouldn't be possible to clean shut-down the PI. Something like that could probably be implemented by using a GPIO and detecting voltage on the board, I would think. The questions and answers on Amazon.com are very interesting. Too bad - this looked very promising. It's frustrating that they would do so much yet leave out something like UPS capability.
