I don't think even most powerful 13.5 motor pulls more than 40 amps. Look at specs of 13.5 reedy or viper motors. Divide the found value to the 7.4 then, you got avarage current that your motor can pull.
Not quite true. Depends how the motor was rated. It could be much more if the motor was tested with no-load, as a lot of them are.

Plugging 8.4 in will help you a bit because the voltage starts out at this level. The higher the voltage, the lower the amperage when there is no change in load.
