A rechargeable energy storage system includes a battery pack and a battery controller. The battery pack has a voltage current temperature module and multiple battery modules. Respective battery modules have multiple battery cells and are operable to store a module identifier that encodes at least one parameter of the battery cells, receive a configuration request from the voltage current temperature module, and transfer the module identifier to the voltage current temperature module in response to the configuration request. The battery controller is in communication with the voltage current temperature module and is operable to send a status request to the voltage current temperature module, receive the plurality of module identifiers from the voltage current temperature module in response to the status request, and compare the module identifiers to determine either a match or at least one mismatch among the module identifiers of the battery modules.

A manhole lifting apparatus comprising a base support assembly and a lifting mechanism. There is a beam structure which extends over the manhole, with a pivot support at one end of the beam structure, and a mobile support at the opposite end of the beam structure. The lifting mechanism is at the central part of the beam structure. The lifting mechanism lifts the manhole cover, and the support assembly is rotated about the pivot support to remove the manhole cover from the manhole.

The apparatus forms a shell (a) composed of an exterior shell () and an interior shell (). The interior shell () contains a circuit, a Printed Circuit Board with a standard interface, such as an USB connector, extending from the interior shell (). An exterior shell groove () accepts the interior shell () into the exterior shell () with the interior shell () secured within the exterior shell groove () by detent and friction interaction. An imprint surface () is formed to receive exterior shell texture () and interior shell texture () including dimples forming a golf ball appearance and logos.
