I was very confused at the title. If you put in a gate/door off the coop/run then just put some hooks on both sides to tie the end posts to. Personally I'm moving my netting frequently. So I try to always set up the area so that the charger is in the best as can be done spot (like the closest point when walking to it) so I can unclip from the battery, leg over, do chores, leg over and re-clip the battery.
I got small 2 joule chargers and switch out batteries that I charge in the house. I took a 5gal bucket and below the lip drill a hole in each side. One side take some wire and hang the charger and put the ground wire through. On the other side put through the wire to the fence-clip. This way when I move it I can pull the wire inside so just the clip hangs out, then wind the ground wire around the bucket and hold it and the ground rod, and my other hand carry the bucket.
I have one for the chicken fence and one for the sheep fence. I got snap on lids so it's real simple.
