I want to make an uninterrupted power supply system for my (future ) home automation system.
Currently I have a 12V 5A SMPS. I plan to use 3.7v Li-ion batteries or lead acid batteries as the backup power source.
I have looked up many uninterrupted power supply circuit diagrams and they are all meant for a linear power supply system.
My concern is whether I can use the same circuit diagram with the the SMPS ?.
The basic system will be as this:
