Method 3 in this link can be used to connect any number of 12 volt RV batteries in parallel so that they are are balanced:

When this can be pretty educational, I doubt it practical use.
99% of batteries die becouse of age, or mishandling so what small misbalance can change here?
I drive dual batteries vehicles for 30 year (talking about wagons and trucks). None of the manufacturers ever made an attempt to balance the batteries. It is always that pretty long cable goes from 1st battery and connects to main clamp on the 2nd.
Would you think that major truck manufacturers could consider battery balancing if that would made real life difference?
Our latest ECO sedan has main battery under the hood, while ECO engine starting battery in the trunk. Talk about well over 15 feet of cable between.
