First get lots of $$$. Mother earth News has old article on pickup made electric cheap- surplus jet engine starter got GPU kit, coupled to transmission and 10 or 12 reconditioned 12 volt industrial batteries with some series and parrellel wiring to get up to 36 volts in steps. tranny for reverse and gear selection for battery voltage selected meant cruising speed of about 20 mph, 35, 50 depending on 12 volt, 24 volt, 36 volt- a golf Cart variable resistor would give 30% variance in speed each voltage, gear combination. 50 to 100 mile range and overnight charging. 500 pound payload instead of 1000 since batteries weighed about 1/2 payload. still about $3000.00 at the time.
