Yes but 1/12 are lighter cars and they race for 8 minutes, so there is less volt drop under hard acceleration and less load. Problems will show up more often with 4 cell TC especially with Mod motors. Some ESC's may have problems with 'power-fail' voltages (ie won't work well on 4 cells) and running without a RX batt means servos will operate slower. Also lap counting problems with PT's will happen more often. These are all things to consider, as ttso says it will be safer to run with a RX batt, without one you may have more trouble.
