Parallel connection of batteries

You shouldn’t overlap wires in SCH or PCB or you can get fooled by connections.

Learn how to do junctions. Either grab a wire in the middle and move it and move it back and it will create a bendpoint, or right-click on the wire and make a bendpoint. Then hold ALT and click on the bendpoint and make a trace from it to the pin. Otherwise you will always be wasting time clicking on pins to see what is connected.
