Transitioning to an EV isn't easy. I feel like I am still learning how to drive. After doing some research online and asking questions in forums and such I have changed my shifting and driving habits. I am now using 1st 2nd and 3rd, and rarely 4th. I am getting from 0-16 MPH in 1st, then up to 28 MPH in 2nd, then 45MPH in 3rd, and cruise at 50MPH in 4th. I am now reeving the engine to higher RPMs about 4000rpm. Hopefully this will help me get more mileage out of the bus as well as be kinder to the batteries so they will live longer. I am also watching my amp meter to keep the amps below 300 as much as possible. With 6V batteries 300 amps shouldn't hurt the life of the batteries if I don't run it there too often.
I did end up getting on I-5 the other day but I knew there was traffic so stop and go was no problem keeping up with the flow!
