i was thinking and i couldnt think of any reason that why this would not work please correct me if i am wrong but lets say i had the battery in a box and wired to a terminal strip then wired them to a 6 pin mini DIN connector , then used a 6pin DIN Cable to another box with with a 6 pin DIN connector then wired to a terminal strip then wired to the other components would this work the 9v battery holders a wired in series so thats 2 leads 2D Cells so thats 4 more leads 6 lead total, so would this work? the mini DIN Cable inner wires are the same awg as the battery leads .
