Battery wire inductance is the main cause of problem, not wire resistance. The wire-inductance causes spikes on the power input. Long motor wires however is not a problem. If you have to use long battery wires, install extra caps on the brushless controller. Reasons, manufacturer statements, rules of thumb, explanation, methods, manuals, suggestions for installing:

You guessed it, that controller uses sinussoidal commutation, therefore less/no harmonic frequencies. They tested the SLS-60-100 for one hour with a 70m (seventy meter) battery cable at 1500Watt load. One of the developers, Rolf Zimmermann, is user RogerZ at RCGroups. Some people in Japan are working on a RC sinussoidal controller too.
More discussion, also about cooling the input caps:
