Thatll give you 24 volts between the. How to make a 12 volt battery 24 volts.

How to connect 4 12v batteries to make 24v. Connect the positive terminals together on the first set with a short piece of wire. Repeat on the second set. Suppose you have four 12v batteries but you want to put together a 24v battery bank. Connecting batteries in series is required if power inverter solar hybrid inverter or ups requires a multiply of battery voltage to work. Thats known as a series connection. You could connect a pair of batteries in series and then another pair of batteries in parallel.
This is a parallell connection. For example an inverter designed for 24v batteries require you to connect two 12v similar capacity batteries in series 2x12v 24v. You now have two batteries connected in series. 24 volt battery series connection. Then you hook the negatives from the first pair to the positives of the 2nd pair. Connect the other end to the negative terminal of the second 12 volt battery.
Using the same series process used with multiple battery flashlights you are able to connect two 12 volt deep cycle batteries together in order to make in essence a 24 volt battery that can power a 24 volt accessory like a trolling motor. Divide the batteries into two sets and secure them to your project. 4 x 12v 120ah batteries can be wired in series parallel to give you 24v with 240ah capacity. Connect one battery cable to the positive terminal of one of your 12 volt batteries. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. Battery cable connections the cables that join your batteries together play an important part in the performance of your battery bank.
Connect the neutral terminals together on the first set with a short piece of wire. Repeat on the second set. 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.
