Not true, to produce the same amount of power with a lower voltage higher currents are needed, which produce more heat. How else could you pull hundreds of watts from a wall socket without the thinner wire melting? Yet we need 12 guage in out little cars...
Batteries can only give so much current out, dictated mostly by their internal resistence. Moving between a 5 cell and 6 cell pack you will still have the same current limit, but higher voltage on the 6 cell pack so higher overall power output.
If you limited the current of the 6 cell pack to provide the same overall power (V=IR remember
) and kept the cars weight the same the 6 cell car would run cooler.
