Rear battery & Fenders....Developing







Murr-E survived re-assembly of the transaxle, hooray!!! The picture above is a mockup of the fenders modified for battery clearance and the rear dual battery frame. I need to create a little more clearance front and back, de-rust the metal, paint it bright yellow and add edge-trim to the battery opening. The fenders will be supported by risers from the battery frame which will be fixed to the chassis. The original fender support had to be axed to make room for the batteries. I have included a picture of my design for the battery frame/fender support.

Murr-E moves under its own power...

After arriving home from the SMARTT Challenge EV Autocross event, I was feeling motivated. The excellent team from McMichael High School won 1st place in their category with their 96V Mustang. It was great to put faces with the names and I learned some things that will come in very handy when I start on Frankenstang such as the issue of clearance from the motor to the steering rack.

I strapped a battery on Murr-E, rolled it out of the shop, hooked up some jumper cables and off we went. I rode it on my knees since I do not have the fenders and seat mounted yet. I cruised to the front yard slowly and set up for a short video which can be found here. I learned during this test that Murr-E on 12V will barely climb a hill even in lower gears. The original plan to use 36V is still in effect.
