House battery charging while driving

Should the house battery charge while driving?

It gets a trickle charge while driving. If you drive long and far enough, it might fully charge it.

Yes it should charge, and much more the a trickle charge.

4 hours driving would get my house battery up to full charge with the standard class C isolation system.

Start you engine and check house volts. Anything above 13 volts means its working.

X's 2 you should get what your engine is putting out. It's not like a trailer being plugged into a tow veh. With that it depends on the wire size. You should have the same size wire going to the batteries, so I would say what ever amps your alternator is putting out you will get the same to your house batteries, but the charge will be limited to what the chassis needs. I think I'm correct...

Actually, with both batteries paralleled, the higher voltage battery is going to flow current to the lower voltage one. The alternator is going to keep outputting until the whole battery bank equalizes.

When you use jumper cables from one running car to the one with a low battery, you can hear the engine speed change, as the alternator output increases.

Okay thanks, so if my chassis battery is full, the alternator will put out max until the hour batteries are full ? Correct

No, not full output but enough to hold the combined batteries between 13.6 and 14 volts.
As battery voltage rises, the battery resistance rises and the amp intake drops.

I dry camp my way from NY to FL and back, every year, stopping many nights in Federal CGs without hookups, Wal-Marts or Travel Centers.

The only time I run my generator, for battery charging, is when I stay more then one night.
Otherwise, at the end of our 5 to 6 hour travel day, my batteries are charged up and last thru the next night, watching Satellite TV, keeping the phones charged, lights, running the 1 cup Kurig coffee maker 4 to 6 times, and some heat on the chilly nights.

BIRD

Your RV probably has a "BIRD" Module, "Bi-Directional Isolator Relay Delay":

"It provides a method of charging the coach battery from the engine alternator and charges the chassis battery from the converter when the coach is plugged into shore power."

Thanks for all of the replies. It seems my C was improperly wired from the factory. This is our maiden voyage. I'll rewire it when I get home in about a week. Meanwhile, I'll just run my generator to keep it charged when dry camping.
