The amps were kind of guesstimates. I looked at one, but never switched the meter over for the others...it's the wattage that I cared about.

The high voltage battery SHOULD have had higher amperage. It didn't, due to a higher internal resistance (of the battery). The bigger batteries (sub C) were able to dump more current. I'll have to try a 8 Cell Sub C pack and measure it.
