Abstract: Conventional internal combustion engine technology has been around for decades and historically has been the primary power source for virtually all industrial equipment. It relies on carbon-based fuels, is loud, polluting, and the machines it powers are expensive to operate and maintain. A self-contained, rechargeable battery system is provided that possesses superior power than comparable diesel and gas engines. The rechargeable battery power system generates zero emissions, is virtually maintenance free, is quiet, and recharges overnight via a standard electrical outlet. The rechargeable battery power system can be installed in new and used construction equipment (light towers, excavators, generators) and may be used wherever a source of power is required, for example, in vans and boats, and in supplemental power systems including smart grid applications. It can be safely used indoors, in neighborhoods and other locations sensitive to the side effects of internal combustion engines.
