1. A receiver assembly, comprising:
a survey field equipment assembly including a housing enclosing one or more survey components;
a battery pack comprising a housing with an interior compartment configured for receiving one or more cells; and
a quick release mechanism comprising:
a pair of magnets each encoded with a polarity pattern to generate an attraction force when the pair of magnets are positioned with mating faces parallel and substantially proximate to each other and with the polarity patterns aligned, wherein a first magnet of the pair of magnets is positioned on the housing enclosing the one or more survey components and a second magnet of the pair of magnets is positioned on the housing of the battery pack; and
a set of electrical contacts provided in a ring for providing one or more electrical connections between the housing enclosing the one or more survey components and the housing of the battery pack.
