Hi guys
Some people here may already know, I am working on a battery monitoring device for mini computer.
Here is a little background info. The computer is powered by 12VDC and backup by a 12V SLA battery. I need a way to tell the computer the main is lost so the computer can shut down safely. This part is solved.
But there are other batteries (backup for other system) that I will need to monitor too. Ideally I don't want these batteries to share a ground. The best I can come up with is this (below image), is there a better way to do this??
Thanks guys!!
