Mounting two batteries - Page 2

Bill, I am the original owner.
For the life of me, I can't remember what the black wire goes to. I'm going out next weekend and plan to do some work on the rig while out and will see where I ran all my wires to. I do know that I had to use white colored wire for when I ran the ground for my tongue jack. The hardware store was going out of business and it was on sale.
I understand making sure that wires be connected properly. I marked those wires, mostly for my own knowledge when I had to disconnect them for some reason a couple of years back. Thank you for asking about them. The colors of my system worked for me, but then I normally do the maintenance. Now having thought about it while writing back to you, I'll mark or tag where the wires go to.

I have a 2007 2720 with two 6 volt deep cycle batteries. Because of how tall they are, when the lids are on the boxes (for travel), the front cap strikes the plastic lid of the battery boxes. Researching dimensions, GC-2 batteries all seem to have the same (tall) dimensions, but 12 volt deep cycles tend to run shorter in height.

A lot of people switch to 6 volt batteries in series, but if I switch back to 12 volt batteries in parallel, and am not a big electricity user when dry camping, what kind of capacities are people buying for a one week dry camping vacation with 4 hours of generator time per day and no solar panels (yet)?

John, if you have a gen and run it for four hours each day you should be fine. What size of battries were you looking to change over to?

+1

Four hours of generator per day, even with a small Honda 1000i, is more than enough to charge the batteries.

I guess my original answer didn't post. I'm looking for batteries under 10" in height. Taking a minimum of an inch off the top of the batteries will lower the caps on the battery boxes and they should clear the cap.

It took about four hours to charge my batteries today. They had gone from 12.55 volts resting to 12.15 this morning after simulating somewhat normal, but conservative use of lights, water, heater.

A Schumacher SC9 charger was connected to the Honda EU2200i. The gennie has an outlet for alligator clips to charge batteries, but there's no protection to prevent cooking the batteries if one isn't checking constantly.

By the time the charger showed a green light, the battery test (resting) 12.91 volts.
