#175383 - Best power to weight battery type?
It's well known that Lithium polymer batteries offer the best energy to weight ration, but does anyone know how I can get the best power to weight battery. I only want power for 30 seconds, but I want a lot of it. People using lead acid batteries say that if you max out the current the cell voltage drops off, but comes back after a recovery period, which means the voltage drop wasn't because the battery was discharged.

Should I be looking at NiMH?
