Help with setting up and using DC120100C SOC battery monitor

That clears it up a bit - Thank you.

- Should I be concerned about the voltage?
- Do I need to calibrate it or is it "good enough" out of the box?

Thanks so much for the video. Such a simple thing and it helped a bunch.

We're not heavy users of the batteries (no 120VAC stuff running off the batt's). However, I don't like getting caught with my pants down if I run out of juice and I could have recharged during the day. I just don't like to "worry". If I worry too much, I run out of beer and, well, we don't want to go there!
