Energy Xtreme’s anti-idling technology, the Independence Package - Law Enforcement Series, utilizes a power management system to operate a car’s full electrical system without engaging the engine. The Law Enforcement Series consists of the LE and the soon-to-be-released LE Lite. A model like the LE, but 50% of the size and weight allowing for more trunk space. The Law Enforcement Series eliminates the number of dead batteries caused by the constant power draw of electrical systems, recharges while the vehicle is driving and can also provide engine ignition power in case of a dead engine battery. Law enforcement departments are using the Independence Package LE to save money on wasted gasoline, to slow wear and tear on vehicle engines and to reduce emissions.
