🔍 Key Concepts

• How series connections affect battery bank voltage while ampere-hour capacity stays the same for that string • How parallel connections affect ampere-hour capacity while voltage stays the same across the branch • Identifying how many batteries are in series per string and then how many strings are in parallel from the drawing

💭 Think About

• Look at each jumper: when a wire goes from a POS terminal directly to a NEG terminal of the next battery, is that a series or parallel connection, and what does that do to voltage? • Then look at the external leads (the heavy arrows): from which NEG terminals and which POS terminals do they leave, and does that show those two series strings being tied together in parallel? • Once you know the voltage of one series string and the ampere‑hour rating of that string, how does putting two identical strings in parallel change the total bank rating?

✅ Before You Answer

• Count how many 12‑volt batteries are in a single series path from the negative output arrow to the positive output arrow • Verify whether the ends of those series paths are paralleled (NEG-to-NEG and POS-to-POS) at the output terminals • Confirm that in series you add voltages but not ampere‑hours, and in parallel you add ampere‑hours but not voltage before matching to the closest choice
