If you have two vehicles geared to go the same speed, but one is running 2 cell and the other is running 3 cell with both having 5000 mah and lets say in a 8 min race. The question is over the span of the race will the 2 cell's power drop off faster than the 3 cell. Thus giving the 3 cell the advantage? Should all vehicles run the same number of cells unless it's called "unlimited open class"? Thanks in advance for your in put.

Quite hard to compare as the motor will respond differently on a higher voltage

If the packs are the same size in mah the 3s driver will have the ability to run for 50% longer (assuming the motor makes the same power)

Cheers
