You can wire an esc to a servo tester and use that to control your motor speed. (You can use a lipo to power if desired rather than the power supply he used in the video) It’ll be variable speed, but you can set it to 50% or 100% or whatever fits your need. Dangerous operations.

I’d be curious to see what you’re building as well as how it works out. Dangerous operations. Disclaimer: I don’t know wtf I’m talking about.

If something says it’s rated for 3-6s, it means it can handle 3s to 6s batteries. HOWEVER, since we’re talking about a servo tester, I think you mean that it can handle 3-6v (3v to 6v). If your esc doesn’t have a 3 wire signal lead (5v, ground, and signal) in addition to the main power wires, then you could connect one of the bec’s linked below to your main power wires, run the 5v output to the servo tester, and run the signal wire from the servo tester to the signal wire on your esc. https://www.mateksys.com/?portfolio=mbec6s Dangerous operations.

See my previous answer. All the servo tester is doing is putting out a pwm signal to tell the esc how much power to put to the motor via a 5v pulsed signal- as long as you’re not putting too much voltage through the servo tester itself (in other words, use the linked to bec to power the servo tester), it doesn’t know nor care what size battery or amount of voltage/amperage is running through your esc or motor. It is strictly a control signal- it is taking the place of your throttle stick on a transmitter. Your transmitter doesn’t know or care what voltage or amperage is running through your quad- it just transmits “power equals 0% to 100%” depending on its value. Servo tester is the same. Does that make sense or am I not explaining it well? Dangerous operations. Disclaimer: I don’t know wtf I’m talking about.

Correct. The esc that you linked to has a bec that puts out 5v to 5.5v on that 3 pin cable depending on what amperage model you have- the servo tester can handle up to 6v, so regardless of which of those esc’s you have, the servo tester will be fine. The 50A and above models of that esc are the only ones that say they can handle 6s batteries, so make sure you have that model or higher in order for your esc to be able to handle your battery.
