    Hello,
    I am thinking about building a cable with proper connectors to be able to connect HV battery packs to cars while they are on a bench. I plan on making it about 8 ft long. I believe 4 gauge should be more than enough for this. Obviously all the safety concerns would be considered. Has anybody done this? Any advice?
    Thank You

    I was thinking about that, but I think I would want heavier wire. Also, I want to make it so it can be used with both gen 2 and 3.
