Hey guys.

I am just using the best 6 of the used batteries that I have.

It looks like 20 miles is about the best I can expect from them.

Going to a larger number of batteries in series should improve my speed and range. However, adding more batteries that AREN'T as good is like making a chain longer with your weakest links.

The charger I am using in the Metro right now is a K&W something or another. It can charge a range of 72 to 108 volts. (You just put in a different resistor to tell it what to output)

Because I don't own a 144V charger, I will most likely go to no more than a 108v system. If I get the original Cougar back in, I think I will play with it at 96V for a while.

The clutch is NOT hooked up as a power disconnect yet. I did a mock-up with a spare Anderson connector, but the actual power isn't running through it yet. I do plan to eventually run it that way. It is the one feature I plan to steal directly from Project Forkenswift. Everything else that is the same between the Electro-Metro and the Forkenswift are merely coincidence.


PS:
I also think that maybe I can make a custom guage panel using "Great Stuff" expanding foam insulation. It is a really dimensional material which is easy to cut and form. I could easily make a custom shape to fit in the cig-lighter/cup-holder area.
Alternatively, a robot arm that would hold all the guages would be cool too. Maybe Tom has a spare one in his basement....
