From my forklift mechanic days...they ran on 48 volt batteries that were BIG, 2,500 LBS big. On take-off you would use roughly 500 amps and cruising was more like 60amps depending on how you set the cards. Of course you could turn down the max amps and get a little more distance, but you couldn't go up a ramp very well. I used to set them to 550 top end and they would fly right up a ramp. (then you have gearing too, I doubt your car will weigh 4 or 5 tons.) The cards had pots on them and controlled the speed/pedel/current relationships. Turns out I was the only one that actually adjusted the cards, and extended battery life and component life by doing so. Most of the other guys just replaced a burned out card and sent the lift out, only to have the card burn out in a week. However you are setting up the system, make sure you stay below the max current and voltage capacities for the components used. If using an analog setup, be sure to adjust all your pots, etc accordingly. I LOVE analog because it is in your hands, not the computer's,LOL. HAVE FUN
(I miss being able to lug around 25,000LBS with a B50)
