    Batteries -- Parallel Wiring -- Buss Bar Advantage

    In several threads the question of how to properly wire batteries in parallel has come up in the discussion. I have found a study that explains the advantages of various wiring schemes when it comes to wiring batteries in parallel...

    Here is the quick explanation:

    According to the study linked below, when the load is connected to only one battery there is a disproportionate draw from the first battery in the parallel string. This disproportional draw is lessened if the load is connected to the first and last battery in the string, however, in a longer parallel string (say 4 batteries) even if you attach the load to the middle batteries the load places a disproportional draw from the battery(ies) the load is attached to. The only way to draw evenly from all batteries in a battery bank is to attach all the batteries to buss bars and then attach the load to the buss bars.

    Here is the study I mentioned...
