Abstract
A battery pack connection scheme is shown that provides an optimum DC environment for every cell in the pack, such that every cell in the same or similar voltage level in the pack sees exactly the same voltage and current environment. In some examples, a portable pack is provided having a positive load connection terminal and multiple batteries connected in parallel to the terminal. Connections are made with segments preferably have matching impedances, or have matching DC resistances, creating a uniform DC environment. Portable pack designs are provided including chargers and inverters connected in the uniform DC environment.
