Question 2 of 5
Battery Configurations

Batteries can be connected together in various combinations to increase their total voltage and/or total current. Connecting batteries in series combines their voltage while keeping their current the same, connecting batteries in parallel combines their current while keeping their voltage the same, and using a series-parallel configuration, half the batteries can be connected in series and half in parallel to combine both voltage and current.

How would you connect 6 [15V 15A] batteries to achieve a combined power output of 45V 45A?
