I am starting on my first larger electric project. I will be running 2 3-cell packs in parallel through a Y harness. My concern is that once you plug one of the male connectors on the Y to the female on one of the packs, the other male on the Y becomes ''hot''. Is anyone else concerned about this, and what approach do you use? Also, does anyone have a link to plans and instructions for Y harnesses? I will be using Deans plugs.
