DC Voltage Monitor installation question

I would like to install this DC voltage meter to tell me the state of my batteries. I have minimal experience with electrical but have been reading quite a bit and plan to eventually install solar. My trailer is a 2015 Jayco x19H with 2 group 24 Interstate batteries installed in parallel (both are connected and trailer runs off both).

Questions are:
  • What do I tie these into? I assume the +- wires coming in from the batteries to the converter. Would I install them between the batteries and converter?

  • how would this differentiate between both batteries? Does it matter or if things got inconsistent just use my multi meter to isolate which battery is having an issue.

Well $5 is certainly cheap......but won't REALLY tell you what is going on with your batteries. Since good batteries (multiples in a bank) can cost between $150- $600
It makes sense to know more, so you can make the batteries last as long as possible ( per cycle AND lifetime)

To answer your question...yes connect to a point as close to your batteries as you can.

Consider installing this instead.....this will REALLY tell you what's going on with your batteries.
