This is how I connect 2 batteries.  Keep in mind Tech's comments on colors.   Here's an old post with some reference:

	While I would hook up two batteries in parallel and connect to the trailer just like this (less confusing to others and even to me), in the case of two batteries both connections could be connected to one battery. Resistance in the lead (unless it is quite long) would not be measurable and with only two batteries no internal resistance comes into play.

	Lots of real-world experience says otherwise. That slight difference in resistance translates into a large difference under load and when charging, over time. The battery closest to the load and charger - which would be the one the pod is directly connected to - will supply the most amps and then accept the most amps. There is no measurable difference in resistance between 10 gauge wire and 14 gauge lamp cord (unless you use expensive equipment), but its there and is pronounced under load.
