For this reason battery performance is usually measured in watts (a unit of energy calculated by multiplying voltage x amperage) per liter or watts per kilogram.
In order to fully exploit the sound potential of the HDVD 800 with any audio source, a rotary gain switch at the rear of the unit provides simple adaptation of the amplifier output to the audio input voltage.
The power electronics unit integrated in the engine compartment operates at a level of around 370V and manages the flow of high-voltage energy to and from the battery and the electric motors.
