Hi, I am a university student in the Netherlands and I just got the assignment of building a robot on a budget. Because of this budget I would like to make the battery pack that powers the 2 servo motors and 2 electric motors myself. I did some research and found out it would be best to connect multiple AA Alkaline (1.5 V 2700 mAh) batteries. I know my basic physics as the current will stay the same and voltage adds up, though what about the capacity? I understand how this battery works but now my question was if I connect for example two batteries do I get a battery pack that can deliver 3.0 V with 5400 mAh, or just the 3.0 V with again a capacity of 2700 mAh. Thanks in advance!
