I agree Sam, Ive tested the golds in a bot and on the bench and you definately can run the 24v at 36v. I used the H5 speedcontroller @ 36v on mine. Ive also driven BlacknBlues spinning bar on a 12v gold @ 24v and whilst the motor was very hot the subC NIMH cells were only warm. The only disadvantage of the golds is weight and cost
