When setting up your RV for a long trip, one crucial aspect to consider is your power supply, especially if you plan on doing a lot of dry camping or boondocking. Many RV enthusiasts face the choice between using a single 12-volt battery and two 6-volt batteries connected in series. While each option has its pros and cons, opting for two 6-volt batteries may provide significant advantages, particularly in terms of durability, capacity, and overall longevity. Let’s dive into why two 6-volt batteries could be a better choice for your RV.
Enhanced Durability and Lifespan
6-volt batteries, often referred to as golf cart batteries, are renowned for their robust construction. Typically, these batteries are designed with thicker plates, which are less susceptible to deterioration over time compared to the thinner plates found in standard 12-volt batteries. According to Battery University, thicker plates present in 6-volt batteries can handle more discharge cycles before failure, making them more durable. More detailed information on this can be found at Battery University's website (Battery University).
Higher Capacity and Depth of Discharge
One of the most significant advantages of using two 6-volt batteries is their ability to handle deeper discharges. Experts agree that deeper discharge capability allows for extended usage between charges, crucial for RV use where power needs are high. The depth of discharge (DoD) in 6-volt batteries can generally go lower without impacting the battery's lifespan as adversely as it would in a 12-volt.
Bob Livingston, a seasoned RV expert, suggests that with two 6-volt batteries offering a total of about 220 to 240 amp-hours, RV owners can enjoy a larger energy reserve compared to a typical 12-volt battery which might provide around 80 to 100 amp-hours. This insight is detailed in his discussions available on RV lifestyle forums and publications (RV Lifestyle Magazine).
Reliability in Series
When you connect two 6-volt batteries in series, you are effectively doubling the voltage to achieve 12 volts necessary for most RV systems. This setup not only provides a higher total amp-hour capacity but also ensures more reliable power delivery. The series connection means the voltage adds up, while the amp-hour capacity of the setup remains that of one battery. This configuration is highly beneficial for evenly distributing the load and stress on each battery, promoting longer battery life.
Considerations for Weight and Space
It's important to note that 6-volt batteries are typically heavier and may require more space than a single 12-volt battery. This could be a consideration for RV owners where weight and space are at a premium. However, the trade-off comes with increased power capacity and durability, which can be worth the extra weight for those who rely heavily on their RV’s battery system.
Conclusion
Opting for two 6-volt batteries over a single 12-volt battery for your RV setup offers numerous benefits, including longer lifespan, higher capacity, and more reliable power delivery. Although they might take up more space and add some weight, the advantages they bring to the table—especially for those who spend a lot of time off the grid—can significantly enhance your RVing experience. As always, ensure that your battery setup is properly installed and maintained to get the most out of your investment. Happy RVing!
In conclusion, while the choice between 6-volt and 12-volt batteries might depend on individual needs and constraints, the dual 6-volt batteries setup is definitely worth considering for the serious RV enthusiast looking for reliability and extended power capacity.
