Kind of an over all view of the drive train and Battery pack. he front red knobs are the high voltage shut off switches so Ican actually isolate the two motors while programming and testing. the total battery weight is 660 pounds, the transmission is about 85 pounds, the two motors combined are 240 pounds, the two controllers combined are 18 pounds... another 20 pounds in cabling the contactor box and shunt / shut off box combined are about 20 pounds. So roughly 1050 pounds.
