Oh, I was doing a bit of math there. I already have a few spare cells... I needed 6,798
more to DIY my own roadster pack.
Poor man's lithium... has it been done yet?

Battery Type: Lithium-Ion )
To do this on the cheap, I have a feeling you'd need an "in" with a company that sells/services lithium powered products ... or even a cell manufacturer. You need access to castoffs/bad modules you can harvest good cells from.
Another way to look at this would be to look at lithium is an investment. Treated properly, you can conceivably get multiple thousands of cycles from your cells, so you could have them for years and years. Even move them from vehicle to vehicle. Per mile, they're less expensive than lead acid. New lead acid, that is.
Nahh... I'd like to see someone do it on the cheap!
