If it pull less current, you can use batteries which aren't specced for high amps.
If use use less amps, you can use thinner cabling and split the batteries up i various compartments. That means heat is more distributed. Less active cooling, if any, is needed, of both batteries and motors.
All of the above can translate to less weight, which mean better range.
