1. The Golf Cart Battery Secret Most RVers Miss

Here’s a mind-blowing hack: golf cart batteries (6-volt batteries) can save you serious cash when wired correctly. You can actually wire two 6-volt batteries in series to create one powerful 12-volt battery for your RV.

How it works: Connect the negative terminal of one 6-volt battery to the positive terminal of the other. Boom—science! You’ve just transformed two 6-volt batteries into one 12-volt powerhouse.

The money-saving magic: You can often snag two golf cart batteries for less than the cost of a single 12-volt RV battery. Just remember you’ll need one cable to connect them, but even with that extra cost, you’re still coming out ahead.
