Does a series-parallel configuration increase battery capacity?
Yes! A series-parallel configuration allows you to achieve both higher voltage and increased capacity. Important Notes: Batteries must be identical in voltage, capacity, and age to ensure even performance. Proper fusing and circuit protection are critical to avoid short circuits and failures.
