A cordless vibratory pile driver ("vibro") may use one or more batteries to provide the requisite power. The cordless vibro may sit in a stand that also recharges the unit while it is in the stand when the device is not in use. The replaceable batteries are mounted as part of the suppressor housing on top of the housing that contains the eccentrics. The batteries are balanced on both sides to distribute the weight evenly. A small battery powered electric hydraulic pump sits in the suppressor housing to provide oil to open and close the jaws. A digital hand held remote control sends the necessary signals to the machine to open and close the jaw and to start and stop the vibration.
