MiscUlanEous Factazoids

Big testing excitement today:

1.) Under any sort of real world load it's become obvious that one of the batteries is failing. Only good for 6-8 miles now and that's without any really high current loading (no 300A blastoffs or hills.) We captured one of the failure events with the datalogger and sent the file off to Sean. He agrees it's bad and apparently it will be warranted. May swap in a battery from the other car to get this one back on the road.

2.) Load test: we went out with four people on the car. Not a long drive or any hills to speak of, but the people weren't exactly lightweight either. It wouldn't hit 45 with four of us in there. Scotty to Bridge: She's givin'it all she's got captn'!

3.) The specs for the new battery management board are pretty much set and Brian may have first prototypes available by mid month. Way to go! Update: Prototype boards arrived and are reported to work exactly as expected. Should have final parts in two weeks. Cool.
