The guys at ProEV have built a really amazing car (the “Electric IMP”) from a lot of the same parts that I’ve been thinking of using. They’ve got tons of details about motors, controllers, batteries, etc. What I’ve been thinking of doing is almost exactly half of the IMP. 1 Siemens, and ~200V with (hopefully) [...]

I like what Valence is offering: LiIon batter packs in the form factor of lead-acid. Fully sealed & contained means they would be a lot easier to work with than the bare cells, and probably have minimal weight difference. No prices on their website, though. Click on U-Charge Systems

http://www.nrel.gov/vehiclesandfuels/energystorage/pdfs/2a_2002_01_1962.pdf They’re “prismatic” NiMH batteries 1 “module” = 6 * 1.2V in series = 7.2V, rated 6.5Ah, weighs 1kg 1 “pack” = 38 “modules” in series = 273V, 6.5Ah Discharge power capability: 20kW at 50% SOC. (25kW = 33hp) I’m not sure how many “packs” per car, but I would assume at least 2, probably [...]

A standard AA-sized Lithium Ion battery (Panasonic, etc.) will produce 3.6V, maximum draw of 95A, and contains 2.4Ah (Amp Hours) of energy. Let’s assume you don’t want to ever draw at 95A, so reduce that to ~50%, ~50A. 3.6V * 50A = 180 Watts = 0.25 hp So, if we want a maximum power output [...]
