I am not sure exactly what your question is.
Most full sized school buses had two 8D batteries wired together (parallel) with positive and positive wired together and negative and negative wired together.
Sometimes, in older equipment, you may find someone has wired batteries in series. In order to get 12-vdc out of 6-vdc batteries you need to wire the batteries in a series with positive on battery one connected to negative on battery two and negative on battery one connected to positive on battery two.
