I put in a temporary hack to adapt the cables coming up on two years ago. It's working OK so I have little incentive to correct it.
Look at original posting for short description and a couple of detail pics. More pics attached along with a shot of the mostly finished cart. This method has the advantage of allowing the battery side of the cables to be easily reused. There is electrical tape now covering the terminal adapter and ziptie. I really should find those Anderson replacement connectors and staple them to the cart in case I get enough energy to install them.
