ABSTRACT:
Hybrid power equipment comprising a user-selectable power selection switch for switching between DC or AC power, a boost and conserve feature for increasing speed of the working elements as necessary, and a motor or a plurality of motors for moving working elements. Running the OPE at the conserve setting prolongs battery pack duration per charge. The motor may comprise a dual coil commutator configuration. Power supply and control systems allow the user to select operation of the plurality motors or dual coil commutators in either series or parallel configuration depending on the power source.
