Abstract

A battery pack connection scheme is shown that provides a synchronized DC environment for every cell (401-405) in the pack (400), such that every cell in the same or similar voltage level in the pack sees exactly the same voltage and current environment. In some embodiments, a pack (100) is provided having a positive load connection terminal (106) and multiple batteries (101, 102) connected in parallel to the terminal. The connections are made via respective conductive paths (131, 132, 141, 142) each including a high-power DC precision cable segment (7H1-10), each of the conductive paths having a resistance suitable to allow an average charge acceptance rate of the battery pack (100) to be greater than a one-hour, or 'C1', charge rate. The precision cable segments (7H1-10) preferably have matching impedances, or have matching DC resistances.
