Paralleling 3 batteries in a balanced setup
Would like to open a discussion on paralleling 3 batteries in a balanced method. There seems to be only one option that is mentioned on the forum. I have suggested a second method that may be easier i...

It is fun but also useful for those that want balanced wiring. What other information is needed for a complete analysis. Seems that all need information is there.

That is exactly what I'm saying! The easiest way to increase the wire size of the cables closest to the take-off point is to put another cable of the same length and size in parallel with it. To balance the resistance of the cables closest to the take-off point needs to be 1/2 the resistance the cables farthest from the take-off point.
