The Electro-Metro is now running at 108 volts!

Even though I put 3 more batteries in a while back, (removed the one group 31 in front and added 4 Die Hard Platinums in its place...) I was still running the car at 72 volts.

I had home problems with the Open Revolt "Cougar" controller, so I was still using the Curtis 1221 (500amp, 72V max) I think the trouble I was having was part environmental (humidity, saltwater, etc.) and partly that I am TERRIBLE at building electronics...

I sent the controller over to Paul Holmes for some tender loving care, where he freshened it up and gave it a coat of - what do you call that stuff? - some sort of electronics clear coat.

I got the controller back recently, but have been too busy to do any more work on the car.

Today, I cabled up the additional 3 batteries in front, and wired in the Revolt Controller.

Then, it was off for a test drive!

It definately has more OOMF! at 108 Volts. Hill climbing is greatly improved. I have several hills in the area that my car has never liked. There's one that I don't try to go up because the car just ends up going embarassingly slow, and there's always a lot of traffic in that area.

I'll get some photos or video soon for you guys to see.

I'm also trying to get the car cleaned up a bit today because a documentarian film-maker is coming over tomorrow. Wish me luck on that one!
