[A/S] Does Distance Make a Difference?

["Edward Emerick" <EEMERICK@xxxxxxxxxx>]

Hello All,
I have to replace my Airstream Univolt III in my 68 Sovereign, or at
least I think so. The current unit does what it is supposed to do,
provide power to charge the battery, however it overcharges because it
does not have some kind of shut off when the battery is fully charged.
So I kill batteries by over charging by not paying attention to how long
the converter is on. All I know is we turn it on, get busy with
something and start cooking the battery. So before I buy new batteries I
have to purchase a new converter (I know that an inverter is better but
the difference in $$$$ for an inverter is not in the budget this year!).
 
Now for the question; to add an additional battery to the system I need
to move them from the rear of the coach to under the bed mid coach which
will add about 12 feet to the current wiring, is this going to cause a
problem? I am worried about the reduction in effectiveness of the
charging system by increasing the distance from the converter to the
batteries.
 
A new converter will have an automatic shut off to keep me from cooking
the new batteries and the new batteries will be AGM or gelcell to keep
from killing us from their placement in a non-vented area.
 
 
Also any recommendations of converters or battery brands will be
gratefully accepted!
