Joining RV batteries in series allows the technician to achieve which result?

Joining RV batteries in series effectively increases the total voltage while maintaining the same amperage. When batteries are connected in series, their individual voltages are added together. For instance, if you have two 12-volt batteries, connecting them in series will yield a total voltage of 24 volts while the current (amperage) that the system can deliver remains the same as that of a single battery.

This method is often used when a higher voltage is necessary to power specific equipment or systems in an RV, such as an inverter or a high-voltage appliance. It is important to understand that while the voltage increases, the amperage capacity, or the total amount of current the batteries can provide at once, does not change; it is determined by the weakest battery in the series configuration. Thus, this connection method is ideal for maximizing available voltage while keeping the same current load.
