Can You Combine Batteries in Both Series and Parallel Configurations? Yes, you can mix series and parallel batteries. Series batteries are connected in such a way that the voltage of each battery is added together while the current remains the same. This means that if you have two 12-volt batteries in series, they will produce 24 volts.
