Charger | Zivan NG3 115 volts AC input and 96v to 144v DC output. | ||||

DC/DC Converter | CC Power C400 This converter failed after four months of use. Neither the manufacturer nor Electro Automotive would honor the warranty or even tell me if there was one. I now use a separate deep cycle battery for the 12 volt system and charge it as needed. | ||||

Top Speed | 70 MPH (112 KPH) This is just estimated. I never tested it. | ||||
Acceleration | Nearly as good as it was with the gas engine. | ||||
