How To Wire 2 6 Volt Batteries In Series. The good news is you can combine series and parallel wiring with 6 volt batteries so you can combine 4 or more and keep the voltage at 12 for your RV but increase the amp hours. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity.
Series-parallel connection is when you connect a string of batteries to increase both the voltage and capacity of the battery system. The connections will be the same. There is series-parallel connected batteries.
Use 2 4 6 or 12 volt batteries to build a system voltage of 12 24 or 48 volts using series and parallel wiring with just 4 clicks.
Connecting in series increases voltage only. For example these two 6-volt batteries joined in series now produce 12 volts but they still have a total capacity of 10 amps. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. The images used here will focus on this setup but if you are using 12-volt batteries simply swap the numbers.
