Battery capacity

I was talking to my brother-in-law last night.  He's got a huge class A motorhome.  We were discussing the advantage to using 6 volt golf cart batteries, both for purposes of available amp hours and battery longevity.  By coincidence we both are using Costco 6 volt golf cart batteries.  After 12 years of pretty heavy use, he's replacing the bank of 4 at about $85 each.  He did say that he was very careful about keeping the battery water level always topped off.  I figured he knew a lot more than me since he's a retired electronic engineer.

I guess that's a good point. A pair of 12V batteries in parallel or using one as a spare would be more fail safe than a pair of 6V batteries. If one of the 12V batteries dies, the other one could still be used. The added bonus of having an emergency backup for your tow vehicle is something that I had not considered. If one of the 6V batteries goes out on you, you are stuck.

Thanks for all the helpful tips.

Dennis, the direct current side if an RPod electrical system s 12 volts.  If you connect two six volt batteries in series it makes 12 volts.  The advantage of this is you can increase the storage capaity of your battery by doing this and therefore the length of time the charge will last when you are using it.

You need to learn more about electricity before you start making these changes and additions.  If you can find a mentor close to where you live that can help you that would be the best.  As another poster said you need to understand the system or you could wind up damaging your Pod or worse hurting yourself or others.
