1. A battery pack capable of supplying at least 50 amps of current, the battery pack comprising:

  • a positive load connection terminal; and

    multiple batteries each having an anode and a cathode, the cathodes of the batteries connected in parallel to the positive load connection terminal via respective and distinct conductive paths, each conductive path having an under-load resistance differing from an under-load resistance of each other path by less than about 1 milli-ohm;

    wherein the multiple batteries each has a similar loaded output impedance, the first conductive paths each having a loaded series impedance at least five times greater than the loaded output impedance of the multiple batteries.
