T500 Maximum Continuous Thrust

[EliotBR (Eliot)]

@EliotBR

I’m not sure if we have a definitive value for the maximum continuous speed command when using a 6S battery, so I’ve asked about that internally. Given the limiting factor is the thruster temperature, it likely depends on the temperature of the water it’s running in.

Following up on this,

While our thrusters may survive full throttle operation for extended periods of time in the right conditions (fluid temperature, supply voltage, system variability across units), it is not their primary use case so we do not have extensive validation data to provide an exact threshold for that application beyond estimation.

For some extra context, in our initial development testing we did successfully run a sample set of T500s at full throttle for an hour in 27℃ water, with a 22V power supply, but there were some issues with extended-duration full-throttle tests at higher voltages (hence the warning about extended full throttle at maximum operating voltage), and we don’t have statistically significant samples for longer full-throttle durations, or for extended durations in higher water temperatures.

@EliotBR

Our thrusters are controlled using speed controllers, which do not technically directly control thrust.

There is some additional context and discussion about thrust at speed in this post, if you want to know more.
