Is it ok to connect two motors (brushed) to one ESC? What will happen to the Amp rating? I have 2 480 motors and want to use one ESC to control them. I know they draw about 11 amps at full load in the water so with 2 of them will this be 22 Amps?

Load will double

Be sure the ESC AND cells can handle it. If 11A is accurate the current being passed will result in 22A with 2 motors.

depends on which way you wire them too .

You mean series vs parallel? How would that affect Amp draw?

corect me if im wrong ryan . one way yes the amps will dubble the other way the volts will and the amps will stay the same . i need to find where i read this it has the pros and con of each

someone here just explained. In series, the RPMs will go down and voltage will be "split" between them the amps will remain the same. In parallel, the voltage will be the same for both but amps will double.

thats it where did you see that i wont to save it

i meant someone here at work (an engineer) explained it to me

Parallel motors is what we used 95% of the time. In the end it equates to more wattage.

Scale boats typically would use series wired motors more than we would as max power is not as much of a concern.

However, since the majority of us use BL motors, this no longer applies for motors/esc's.

EDIT:
Current will drop since voltage drops. You will see less overal current for 2 motors in series vs 1 motor. In other words you will get more overal power from 1 motor than 2 motors wired in series.

Sorry guys i know this twin motors forum,
do you know if is possible to run a 7.4V 4000mAH 10C lipo battery in the Pro Boat Blackjack brushless with stock Motor and Esc with out the programmable module.

Thanks.

Of course not, 4 * 10 = 40Amps. That boat draws more.
