1. A portable percussion massager comprising:
a massager housing having a body and a handle;
a battery housed within the massager housing;
a motor positioned within the massager housing;
a percussion massage assembly having a crankshaft, a rod having a first end and second end and a piston having a first end and second end, where the crankshaft is connected to the motor and the first end of the rod is connected to the crankshaft at a point offset from the rotational axis of the crankshaft and where the first end of the piston is coupled to the second end of the rod, where a node mount having an interior is in communication with the second end of the piston, and where the percussion massage assembly is configured to percussively move the piston along a reciprocation axis relative to the massager housing in response to the operation of the motor; and
at least one temperature-controlled massage node comprising a node housing having an upper portion and lower portion, where the lower portion includes an outer sleeve and where the temperature-controlled massage node is removably coupled to the node mount by the outer sleeve frictionally fitting within the interior of the node mount, where the temperature-controlled massage node includes a Peltier plate, and where at least a first electrical contact is located on the lower portion of the node housing and at least a second electrical contact is located in the interior of the node mount, where the at least first electrical contact includes an electrical pin that makes an electrical connection to the at least second electrical contact when the lower portion is coupled to the second end of the piston.
