If you install a second battery in the caravan link the two together as shown in drawing two then connect the positive from your solar regulator to the positive on battery b and the negative from your solar regulator to the negative on battery a that way any voltage drops will be equal between the two batteries. Following this example where there are two 12v 200ah batteries connected in series we will have a total voltage of 24v volts and an unchanged capacity of 200ah ampere hour.

How to hook up two batteries. This video is a quick video on how to connect two 12 volt batteries. Adding another battery is a good idea if you want to add a powerful stereo subwoofer system cabin lighting electric windlass wakeboard ballast pump or any of the other electrical and electronic accessories we all want. However some power inverters require a 24 volt dc power source. The installation can be as simple as connecting two batteries in parallel to make one larger battery bank. Check out the diagram for more info. Powering such an inverter requires wiring two automotive batteries in series to make the inverter electrical circuit work.
Connecting two batteries will double the life of a battery when in use. In parallel the voltage stays the same and in series it is doubled. Many power inverters utilize a 12 volt dc power source such as an automobile battery. For my trolling motor i can troll for 5 hours. There are two ways to wire up two batteries. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity.
One way doubles the volts of the two batteries and the other keeps the same amount of volts.
