I got all my used gel batteries back from the battery shop.
The bad news is that most of them are in poor condition.
Two came back with a giant BAD magic markered on the top.
6 of them are really usable. That leaves 10 that ain't so good.
I sorted out the 6 best to put in the Metro.
It looks like possibly the best way to go is to keep the car at 72V right now. I am not sure how much better range I would get by adding 6 more batteries of poorer quality, especially since I don't have individual battery monitoring.
Maybe I start saving my money for a set of 12v deep cycle boat batteries at some point in the future.
Last night, I took the Metro to the
Urban Ecology Center in Milwaukee. I, Swee, and Mike Mangan all gave short presentations on our vehicles, and then had them on display for show and tell afterwards. Mike's electric Harley Sportster was very popular.
Also, I got an e-mail from a new Alt. Vehicle friend I met a few weeks ago. The closest highschool
Electrathon team to me is having their final competion out of town this weekend, and their ammeter just blew out. I am going to grab the one out of the Metro to loan to them. Their last "build day" before they leave is tonight. I might take my motorcycle out there to show off to them while I'm at it.
