What is the difference between "rated current" and "rated load current"?

Hi friend, Rated current is the current when the equipment works normally. Load current is the working current of the load of the equipment. For a power supply device, if the load current is higher than its rated current, it may cause it to overheat or even burn out, etc. Thanks!

Can you use a 2s 7.4v battery with these motors

Sorry the operating voltage range is DC 3.0-3.7V DC.

How much weight can the motors lift if fitted in a quadcopter?

These motors are very small and lightweight,the 4 motors are just about 20g.

why does it say 2s when the rated voltage is 3-3.7volts?

Dear,so sorry,it only used for 1S,and the rated voltage is 3.7volts.
