Hi all,

I want to run my pi 24/7 and need some sort of battery backup.

When AC power is present the battery needs to be charged and the pi must be able to draw power at the same time.

When AC power is lost the charged batteries should take over to power the pi for as long as possible. A couple of hours would be nice.

I am thinking of a battery or super cap. Which one would be better and how i can connect these for automatic switching?

Looking forward for your suggestions!!!

Regards
