Connecting batteries in series means connecting the terminal of the first battery to the terminal of the next battery. This supplies more cranking power than even two 12 volt batteries wired in parallel.

How to connect 8 12v batteries to make 24v. My guess is that i will make 4 strings of 2 batteries connected in series. Each battery you connect in series increases the voltage of the battery bank. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. Connect the red cable from the battery on the left to the red terminal on the battery closest to it. For example connecting three 12v batteries in series with 24v inverter will damage it. Now the two batteries on the ends will make the system 24v while the six in the middle will add to the capacity of the system.
This is a common application needed to supply power to a trolling motor requiring 24 volts. Connect the positive terminal of the first battery to the negative terminal of the second battery with a length of battery cabling as short as possible to accomplish this connection. Connect the black cable from the battery on the right to the black terminal of the battery closest to it. Before connecting batteries with inverter or ups check its specifications to make sure what battery voltage and battery type it can accept. 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. 24 volt battery learn how to connect two 12 volt batteries to make one 24 volt battery unit.
Then wire the positives of those 4 strings in parallel while also having the negatives of the 4 strings wired in parallel as well. I saw a post about wiring 6 batteries but not on how to wire 8 batteries. Four 12v batteries connected in series the total. Connect the positive terminal of one battery to the negative terminal of the other battery see illustration. Two 12v batteries connected in series the total voltage is 24v. Connect a length of battery cabling to the positive terminal on the second battery with the other end connected to your starting motor.
Does anyone have a schematic or drawing on how i should do this. Some larger trolling motors will require 36 volts by connecting together 3 deep cycle 12 volt batteries in series. Never connect more batteries in series than acceptable voltage. Here are a few examples.
