In a battery bank with only series connections, there is only one path for the current to flow. It may be necessary to connect more than one series string of batteries with a parallel connection in a battery bank to achieve a desired amount of energy storage capacity. If there are two parallel strings of batteries, it means that any current entering or exiting the battery bank has the choice of two different paths that it can take. Current always has a preference for the path of lowest resistance, so if one of the parallel paths has higher resistance (longer or smaller size wire) then less current will follow that path. This can mean that one parallel string of the batteries will have to work much harder and will ultimately fail prematurely. Therefore, it is very important to try to design a battery bank to use only one series string of batteries or to make sure that the wiring in th battery bank is done properly.
