Is there a battery that can supply 55 amps to 4 motors in parrallel?
The battery in your car will probably do it, as others have said. That assumes your motors are 12v motors. The instantaneous power output won’t tell you how long the battery will carry the load. Batteries are rated in AMP-HOURS, and that is what you need to know if you are trying to determine how long the motors will run.
