I recently overheated my ME1003 spinning out continuously in snow that was deeper than the vehicle could handle. I decided that it would be a good time to do a partial tear down/rebuild as well as a 72V system upgrade. A couple people have expressed interest in the kart which has prompted me to start this rebuild thread.
The kart body has been heavily altered. It is an American Sportworks Carbide 150cc 2 seater. I came across it on ebay as a barn yard find that had been only slightly resurrected by a tractor mechanic. I cleaned it up and drove it for only 2 minutes before arriving at the conclusion that the 150cc motor was woefully inadequate and too loud for my taste. Out came the gas engine and transmission and up it went on craigslist.
In went a ME1003, Alltrax 7245 and a 16S CA100 pack. This was the kart when it was set up for 48V.
My friends and I often drive it at a large outpatient surgery parking lot (after business hours). We set up auto-x style courses and race each other for time, its lots of fun but quite stressful on the overall system as it sees high load and short cool down periods. It gets driven pretty hard. Sliding into curbs, spin outs, locking up tires under breaking and an occasional collision with a tree or post is not out of the ordinary for this thing (the astute will notice the front fender is slightly crooked from an overzealous operator). The battery pack and motor have seen lots of high duty cycles. That being said, I have had no complaints about either and before the motor died, the 48V setup had about 30hrs of use, plenty of which was at 100% throttle.
Here is a video of it in action a few days before I killed it.

Some of the carnage evident after opening the motor case.
