I'm trying to wrap my head around the concept that a 24v tm with 2 batts will last longer than a 12v with 2 batts. It has been explained that the 12v would need to run on a higher setting to achieve the same speed but my question is if the boat weight and the speed are the same it seems like it would require the same amount of energy regardless of what setting the motor is running on. Are the 12v motors less efficient than the 24v?
