Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
This is not a "yes or no" question. There are people who get along great with one 12 volt deep cycle battery, others need 8 golf cart batteries.
How big are these (golf cart batteries?), how will they be charged (cheap converter, expensive converter, large inverter/charger, truck alternator), where are they located in your RV, are you going to dry camp, do you have an inverter? Much more info is needed.
Just put 2 new 6 volt batteries in series...should I get another pair and hook them up in series/parallel? What is best?
Whether to add batteries certainly depends on how much capacity you need. IF you are adding batteries you should (must) add batteries of the same exact type and capacity. So that is 6 volts, same brand and model number. Purchase two identical 6 volts batteries and wire those two in series. Then those two are connected to the other two in parallel so that you have 12 volts. You shouldn't add new batteries to an old battery bank. Within 6 months is OK IMO. But if you mix battery types and age it will cause the all the batteries to have a shorter life.
