Claim:
1. A modular battery pack system comprising: a plurality of battery sub-modules operably connected in parallel; an isolation system configured to discretely isolate any one of the battery sub-modules from supplying power to a host system, the isolation system comprising an ORing field-effect transistor (FET) for each of the battery sub-modules, with each ORing FET operably connected at its input with an output of a corresponding battery sub-module and operably connected at its output with outputs of the other ORing FETs; and a conditioning system configured to discretely isolate any one of the battery sub-modules from the remaining battery sub-module(s) for conditioning of the isolated battery sub-module by discharging at least a portion of the battery sub-module, wherein each battery sub-module is connected to the conditioning system via a FET, such that conditioning is selectively applicable via the FETs to any one or more of the battery sub-modules.
