I've got a 72v system using 9 8-v Eveready golf cart batteries and an Alltrax controller and a D&D motor on a 1971 Beetle -- basically a Wilderness EV setup that I bought almost finished.
I'm finding a maximum range of 10 miles in mixed driving, which seems low. Since I don't know the car or the batteries or the motor I want to know if I'm way off and what to do about it. I understand that the batteries may not take a full charge if they are new, but I had it up to 76.9 volts today; I also understand that the motor brushes need to run for a while, but I don't know how long or how much difference this would make. I don't have any idea how many hours are on the motor, but not many I'd guess.
Other than that I wonder about tire pressure, transmission losses, etc. It seems to shift fine and the tires are about 32 psi (more than the Beetle wants). Any advice for this new EV owner is much appreciated. I've been doing a good job with the volt and amp meter on the system -- many thanks for the replies to my last thread. I can even now connect my computer to the controller and get a mountain of data, not much of which means anything to me offhand, but it did tell me that the throttle is going to 100%.
Should I worry or will this improve do you think?
