While we have frequent grid power outages, I am looking for a solution to backup my low-consumption LAN/WIFI 12V devices.
Devices consume apprx. 1A @ 12V and I have a DC-DC step-up/down converter to give exact 12V they need.
I’m also having a 14Ah 12V AGM battery, which I plan to use.
So I was deciding on buying Automotive IP65 Battery Charger @4A version.
Main question: will it preserve the selected charging mode after AC power lost and restored? And will it continue charging after AC power restored?
