This is called a series parallel configuration. You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank.
Connecting Batteries Together For More Battery Storage
How to connect 6 12v batteries to make 24v. Most batteries are rated at 2v 6v or 12v so you will need to connect them in series in order to reach the voltage you require. 24 volt battery learn how to connect two 12 volt batteries to make one 24 volt battery unit. Connecting batteries in series means connecting the terminal of the first battery to the terminal of the next battery. To use 6 12v batteries in a 24v system you need to wire them in 3 parallel strings of 2 in series. Some larger trolling motors will require 36 volts by connecting together 3 deep cycle 12 volt batteries in series. To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative.
Each battery you connect in series increases the voltage of the battery bank. That means wire 3 sets of batteries with the plus from battery 1 to the minus of battery 2 plus from battery 3 to minus of battery 4 and plus from battery 5 to minus of battery 6. Connect 4 in series to boost voltage to 24v. Connect the batteries connect the batterys positive terminal to the positive terminal power lead of an electrical device with a battery cable. Connect two 6 volt batteries in series to make 12 volts. This is a common application needed to supply power to a trolling motor requiring 24 volts.
With enough patience and the careful following of instructions 12 volt batteries can provide 24 volts of battery of energy in no time. Each 6 volt battery pair operates as a single 12 volt battery. 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. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity.
