MetroLectrical (lithium-ion Geo Metro electric car)

Turns out that I don't think the problem was controller overheating. I think that the 12V chassis ground wires for the relays and contactors had worked loose, and thus the contactors had just opened and cut power to the controller.

Welcome to EM! Fantastic conversion. Like others said, the range is great.

PS - I took the liberty of trying to fix your YouTube video, but I failed. I also did a new "test thread" of the video and got the same behavior. I think it's a YouTube glitch.

How do you like the thundersky batteries? I read an article about someone building an electric vehicle that used them and found that they didn't meet claimed specs and I would mind a lithium battery for my citi-car, nd if your pricing of $9,000for 36,000 watt hours of battery is correct, then that is only twice the cost per usable watt hour compared to lead acid batteries, that is if they really work.

I've fixed the YouTube link in the first post. Bill, CarloSW2 - can you confirm you can see it?

Ryland, so far I'm happy with the ThunderSky cells. There are the older LCP cells, but I think you'd probably want to go with the newer LFP cells now. The only issue I've encountered so far is that the cells get too hot when I pull more than .33C out of them, so I'm going to have to install an active cooling system. I'd suggest installing three times the Ah that you think you'll need in average amps. For example, if you car will be pulling 100A in average driving, then install 300Ah worth of cells.

I tried the video link, and it still didn't work. So I've just edited it now and put in the exact YouTube search phrase that brings up my video first.
