Hi I need to wire together two motors and a solenoid actuator together but have no idea what batteries would be best or if I should wire in parallel or in a series/parallel hybrid. The motors are rated at 6V, 300ma. The solenoid is rated at 4.5 V and the current draw is unknown. They need to all run at the same time and the motors at full speed. Thank you for reading, for any answers, and for your time.
