Connect a length of battery cabling to the positive terminal on the second battery with the other end connected to your starting motor. Some larger trolling motors will require 36 volts by connecting together 3 deep cycle 12 volt batteries in series.

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