I decided to try another setting in the Kelly controller, one that would use less battery AMPs, and hence less acceleration. There must be hundreds of different combination's one can do with this thing, and they really don't come with any explanation on what they do.
I went over the mountainous journey, and instead of looking of power required to hold speed, I looked at the battery power needed to climb the mountain. It was quite frightening! I was pulling 250 AMPs for 3 minutes going up, and with some simple math the power it took from the battery pack was: 250 AMPs per Hour/3600 seconds per hour*180 seconds driving time*2 for Puekerts Effect = 25 Ah from the batteries! Thats 1/5 of my battery pack, and that was done three times after 12 miles of driving! No wonder I literrally crawled home! I used up at least half my pack driving 3 miles of mountainous hills, more than I expected. Now I know, avoid that part of town.
I have a few new routes I found using MapQuest that I want to try because they are basically flat, and will get me to where I want to go, hopefully with lots of power left.
