Back-up supply on volumio

Thanks DVO.
As I said in one of my previous posts I have always got a written spare up to date SD card to hand for quick changeover.

Use a Strompi3 Line voltage monitor, with a backup battery attached. Cost approx. 70 euro’s.
Using the strompi2 myself with a tecknet powerbank. (has feedthrough).
So the battery powers the Pi and the powerbank is being charged by the net.
And the 2nd power imput on the Strompi is connect to your normal Powersupply.

Thanks, but not really suitible for my system. see my previous posts in this string.
