Hi @Superuser007 -
As noted on the product page for the T200:
Note that nominal operation at 12-16 V is recommended for the best balance of thrust and efficiency, though operation at up to 20 V is allowable. Exceeding 20 V is not within the rating and not recommended, please see here for more information.
If you use the T200 at this voltage but limit the maximum throttle to ~ 1750 / 1250, the stators in the motor will not overheat and crack leading to corrosion damage.
Also, note that the current rating for the switch is small - it is perfect to use as the safety-cutoff switch with the Thruster commander, but it can’t handle the power going to the thrusters through it.
