Ask PYS: Power

Should My Battery Monitor Be Set For 12V or 24V?, on May 08, 2018 asked:

Changes to the electrical on the boat look great but I have a couple of questions. Is the battery monitor, monitoring the house batteries only? Should the battery monitor be set for 12v or 24v? Looking forward to getting out on the boat and testing everything out! - Dave

Glad you like our work. We definitely appreciate the opportunity of improving your vessel.

Battery monitors are designed and built to monitor deep cycle (aka house batteries) and that is what we are monitoring on your boat.  Battery monitors will automatically adjust to a 12 VDC or 24 VDC boat... there is no settings to be entered. - Jeff
