I'm setting up an electric fence to go around all of my animal pens. We have raccoons here and I've seen them numerous times sneaking into the pens and eating the feed (at least it's just the feed!). I'm trying to figure out exactly what parts I need to set this up. So far, I know I need; A fence charger. I was looking at this one: http://www.amazon.com/Fi-Shock-SS-7...898675&sr=8-6&keywords=electric+fence+battery Wire: I'm interested in the polywire A grounding rod: Does it matter how tall it is? Wood post insulators: My fence is made of wood, so I want to use these ones. Can I use a charger like the one I posted above with a battery? Like a car battery? Would I need anything additional for that to work? I like this type of setup because of how simple it is and because of the low cost. Am I missing anything else? I think I'd need something for the gates. TIA!!
