Ahh, but 120 1.2v cells in series (as per your example) charging at 100 amps, are still getting 100 amps per cell. You have to put them in parallel to reduce the current. So you'd end up with 100x100 cells, or 10,000 total.
Edit: Tesla's batteries do actually have that many cells - around 7-10,000. They have a bunch in series to get the voltage needed, then they parallel that enough times to give the amperage needed. The Insight's NiMH cells are absolute monsters to be able to take 100 amps each, for tens of thousands of cycles, for potentially up to two decades.
