Default Weight vs mah

Obviously as you go from 3200mah to 5000+ mah the batteries become heavier. Since 3200 mah is more than enough to finish a race. There must be some point of diminishing returns (9000mah??) where the wiehgt of the battery slwos you down a lot more than the extra punch from the battery.
At least in theory wouldn't a high 'C' lower mah lighter lipo have its advantages?
A 3200 40c could delver more instantaneous power than a 20c 5000mah?

I don't quite agree. I run modified with GM 4200mah 45C, and it is more than enough!

yeah 45c is plenty! but i think a higher c rating is better for a low turn mod motor like a 4.0 but in the grand scheme of things i guess the c rating doesnt make that much difference. i mean orion just released 90c packs. what the hell are those for

I routinely see 45amps on the datalogger running boosted 17.5. Assuming the battery isn't making a car overweight, there's no sense in slowing it down with a low mAh and/or C-rating.
