After reading the recent posts regarding the Surepower 1315,
Vitrifrigo, aux battery wiring, etc., I was curious if a battery
charger or Progressive Dynamics converter/charger would charge the
batteries separately or in the combined mode. So I went down to the
garage to grab my battery charger and volt meter. The charger was
connected directly to the aux battery terminals and then I metered the
two main terminals on the Surepower 1315. They read the same as the
charger voltage meter, so the batteries were combined. This is NOT a
good thing when you have a deep cycle battery in need of a good de-
sulfating charge. My starting battery is a plain old group 41
Interstate. That got me thinking that I should install two battery
shut-off switches to manually isolate the two batteries. The switches
would also provide emergency shutdown of all 12 volt power and I
suppose it could be used as a theft deterrent, too.

Any thoughts or experiences relating to this setup?
