Claim 16:
17. A modular battery pack comprising:
a plurality of modules;
a pack controller;
a positive power bus having a first plurality of connectors;
a negative power bus having a second plurality of connectors; and
a control bus coupled to the pack controller,
wherein each said module further comprises:
an enclosure;
a plurality of series connected battery cells contained within said enclosure, said plurality of series connected battery cells being electrically isolated from said enclosure, and wherein the plurality of series connected battery cells is defined by a first battery cell, at least one intervening battery cell, and a last battery cell;
a positive terminal configured to be coupled to the positive power bus of the modular battery pack via a first connector, said first connector being one of the first plurality of connectors;
a negative terminal configured to be coupled to the positive power bus of the modular battery pack via a second connector, said second connector being one of the second plurality of connectors;
a first relay contained within said enclosure and connected between a positive terminal of the last battery cell and the positive terminal of the battery module, wherein the first relay controls connection of said plurality of series connected battery cells to said positive terminal, said first relay being of a first distinct relay type;
a second relay contained within said enclosure and connected between a negative terminal of the first battery cell and the negative terminal of the battery module, wherein the second relay controls connection of said plurality of series connected battery cells to said negative terminal, said second relay being of a second distinct relay type; and
a control bus connection that provides a control signal input for activating said first relay and said second relay,

wherein the positive terminal of each of the said plurality of modules is coupled to the positive power bus via the respective first connector,
wherein the negative terminal of each of the said plurality of modules is coupled to the positive power bus via the respective second connector,
wherein the control bus connection of each of the said plurality of modules is connected to said control bus that is coupled to the pack controller, and
wherein the plurality of series connected battery cells are connected to the positive terminal of the battery module and the negative terminal of the battery module in response to said first relay and said second relay receiving the control signal input.
