Battery Monitors

How do I monitor the two groups of batteries on my Class A Diesel pusher - 2021 Coachmen Sportscoach 354QS? I have 4 - 6V coach batteries and 2 - 12V chassis batteries. Do I monitor all 10 separately? Or each group individually? What kind of monitor could combine the 6 & 12V monitoring. How is it installed? Thanks in advanced.

Your 4, 6 volt batteries are wired up as 1 large 12 volt battery. That gets a monitor, often installed on the negetive cable.

The chassis battery only needs a volt meter to monitor its charge while using shore power. It's not used except when driving.

4 house batteries and 2 chassis batteries equal 6, but you said you have 10.
Do you have 8, 6 volt batteries.

They would still be monitored as one.

You need a shunt type battery monitor for the house batteries where the shunt is placed on the single negative cable from the batteries so it picks up all loads and charging sources.

A really good one is Victron followed closely by a Renogy monitor. But for an inexpensive but comprehensive monitor check out Qworks on Amazon. Less than $50.

Correct, 8 batteries, not 10

Apologies. Ok, so the house batteries are treated a single 12-Volter and the single monitor would take care of that. Would the monitor also let you know if one of the 6-Volters went bad? Also, I hear you say that the chassis batteries wouldn't need a monitor? Thanks

Monitors are like gas gauges for battery banks.
They don't monitor condition of each battery.

You can split up the batteries one a year or so to check each one but in most cases, if one is failing, the rest are soon to and should be replaced as a group.
