That is completely opposite to what I noticed in 1/12th 10.5 blinky. Higher capacity have a slight power drop off after 2mins, lower capacity warm up and hold the voltage longer. I dont pretend to uderstand why but I have been told that its something to do with the optimal temp and internal resistance. Lap times seem to confirm it.
High C rating does give more punch and may give an edge in 10th TC but I have a £20 practice battery from China that "feels slower" but lap times aren't any different
I certainly wouldn't run extra weight to gain a few hundred mah,the motor would have to work harder for a start.
