1. An improved battery pack for high voltage/high current toy vehicles having high performance features, said battery pack comprising:
- a first row of a plurality of individual battery cells;
a second row of a plurality of individual battery cells;
wherein said first row and said second row are configured in a stack parallel relationship such that said first row is on top of said second row and each of said battery cells are electrically interconnected to define a single direct current power source with a defined voltage equal to the combined total of the voltages of the individual battery cells in both the first and second rows;
said battery pack further comprising rigid casing having an upper outer casing portion and a lower outer casing portion that mate together to form in internal space within said casing that houses said power source, wherein said upper and lower outer casing portions include complimentary cut-out portions in their respective end portions such that they define gas relief vents at each end of the rigid casing, wherein said gas relief vents prevent pressure from building within said battery casing as a result of heat from the power source and allows gas emissions from a damaged or decaying battery cell to be dissipated from the casing; and
further wherein said lower outer casing includes a recess in a forward end thereof, the location of said recess on said forward edge corresponding to a value of the defined voltage and enabling said battery pack to be inserted into a battery compartment of a toy vehicle that is designed to operate with said defined voltage; and
further wherein said battery pack includes a pair of electrical contact terminals for facilitating an electrical connection with electronics on the toy vehicle, thereby providing a power source for operation of the toy vehicle when said battery pack is installed therein.

15. An improved battery compartment and battery pack for high voltage/high current toy vehicles having high performance features,
said battery compartment comprising a compartment in said toy vehicle designed to receive a battery pack, said compartment including a rotatable locking device at a rear end of the compartment and a lug at the forward end of the compartment that extends into the interior space of the compartment, said lug being located at a position that corresponds to a defined voltage of a battery pack that said compartment is designed to receive, and further wherein said compartment includes slots on the sides thereof that are operable to only allow a battery pack having ridges corresponding to said slots to be installed in said compartment, and further wherein said locking device is operable to push the battery pack forward in the battery compartment when rotated to a forward position within said compartment, said forward movement causing the ridges on said battery pack to slide into said slots on the sides of said compartment, said compartment further including electrical contacts; said battery pack comprising;
a first row of a plurality of individual battery cells;
a second row of a plurality of individual battery cells;
wherein said first row and said second row are configured in a stack parallel relationship such that said first row is on top of said second row and each of said battery cells are electrically interconnected to define a single direct current power source with a defined voltage equal to the combined total of the voltages of the individual battery cells in both the first and second rows;
said battery pack further comprising rigid casing having an upper outer casing portion and a lower outer casing portion that mate together to form in internal space within said casing that houses said power source, wherein said upper and lower outer casing portions include complimentary cut-out portions in their respective end portions such that they define gas relief vents at each end of the rigid casing, wherein said gas relief vents prevent pressure from building within said battery casing as a result of heat from the power source and allows gas emissions from a damaged or decaying battery cell to be dissipated from the casing; and
further wherein said lower outer casing includes a recess in a forward end thereof, the location of said recess on said forward edge corresponding to the location of said lug in said compartment, thereby enabling said battery pack to be inserted into said compartment of said toy vehicle; and
further wherein said battery pack includes a pair of electrical contact terminals for facilitating an electrical connection with said electrical contacts in the compartment of the toy vehicle, thereby providing a power source for operation of the toy vehicle when said battery pack is installed therein. - View Dependent Claims (16, 17, 18, 19, 20)
