Lithium Ion is probably the superior in terms of power to weight. Nickel Metal hydride is cheaper, but quite superior to older batteries like NiCad and Lead Acid. (Lead Acid though can support millions of charge/discharge cycles - I don't think any other battery can compete in that parameter, except maybe fuel cells) Correct me if I'm wrong. -WaV
