FIT0482 motor minimum voltage?

Hello, we're designing a circuit with this micro metal motor and want to know the minimum reliable operating voltage? Ideally, we'd like to design it to run directly from a 3.7V lipo battery, and those batteries discharge down to about 2.8V to 3V. Can the motor operate that low reliably? We'd prefer to avoid including a boost circuit for the battery.

Thanks!

You can try the high ratio version to increase the torque: https://www.dfrobot.com/product-1437.html
