What would be the terminal voltage and ampere-hour capacity of the battery bank illustrated if each battery was rated at 75 ampere-hours and 12 volts? EL-0107

Correct Answer: Option B — 24 volts and 150 ampere-hours

The battery bank is configured in a series-parallel arrangement consisting of two parallel pairs connected in series. Paralleling two 12V, 75Ah batteries increases capacity to 150Ah at 12V; placing two of these pairs in series doubles the voltage to 24V while maintaining the 150Ah capacity.
