Buss Bar Method of connecting batteries

It’s almost common knowledge that the more batteries you have in parallel, the more difficult it is to evenly charge them. This is why we prefer the buss bar method of connecting batteries instead of the ol’ series-parallel method. Using buss bars distributes what I like to call, charge/discharge impact over more batteries so that they all are treated as equally and fairly as possible. Charge/discharge impact is the extra use and abuse of the batteries that the leads connect to for inputting and outputting power. The thing to understand here is that the batteries connected to the leads do most of the work, they cycle deeper and more frequently, while the interior batteries just replace what was consumed from the battery ahead of it. See the diagram below for a demonstration of this idea.
