Hello, I am looking for a recommended reliable design of a 12V lead acid based ups.
The purpose is to power a couple of arduino boards, and a 12V router modem so as to have an uninterruptable arduinos - Internet connection.
The total current is estimated to 2.5A. The battery would be a ~10Ah one
I was thinking of a ~ 2.5 - 3A current injector based on a 15V linear regulator powered by a 18V laptop power supply. The current would flow untill Vbat ~ 13.5V.
Thanks for your help
