When I was thinking about adding a charge point the the SS I wanted to make it durable enough to actually jump the SS off.
I went to NAPA and bought these gray and blue battery disconnects. When I got back home i noticed the blue was way to big.
So I used the gray connectors and the heavy 4 gauge wire. You terminals need to be soldered on very well. So heat them up for a while with a propane soldering torch and then stick the solder to them. It will suck the solder deep into the connector ..
I run two batteries and ill do a how-to on that later...
Here are some pictures of the jump point.
