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

Joining RV batteries in series allows a technician to increase the total voltage while keeping the same amperage. When batteries are connected in series, their voltages add together, resulting in a higher total voltage output. However, the capacity in terms of amp-hours remains the same as that of the individual batteries because the current (amperage) flowing through the series circuit is identical to the current flowing through each battery.

For example, if two 6-volt batteries with a capacity of 100 amp-hours are connected in series, the result will be a combined output of 12 volts (6V + 6V) with the capacity still at 100 amp-hours. This configuration is ideal for applications requiring higher voltage while maintaining the same amperage capacity. Thus, this setup is often employed to ensure that devices needing higher voltage can perform effectively without altering the overall storage capacity of the battery bank.
