MMM vs MM with A123's.. Check this out boys :D

[RC-Monster Mike]

I must be missing something here with these graphs and your stated runtime. The MM shows a lower peak current as well as a lower average current draw - I get that(still not enough info to conclusively make any accurate determinations). But...the posted MMM graph only shows 512mah of usage for a 2 minute run, yet you say you are only getting 3 minutes of runtime? My math says you should get nearly 9 minutes at that average current draw (15.5amps)with a 2300mah pack. I say we need a longer run graphed out in order to make any sense of the comparison - a few complete runs on each setup would be helpful, actually, but something isn't adding up. :)
