Nope, no voltage regulator is included.

That’s incorrect. As per the [technical details](https://bluerobotics.com/store/thrusters/t100-t200-thrusters/t200-thruster-r2-rp/#tab-technical-details) the T200 is rated for 7-20V powering (so your 14.4V battery should work fine, assuming it has the current and energy capacities you want/need). In addition:

> 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](https://discuss.bluerobotics.com/t/r3-esc-does-it-allow-me-to-use-24-volt-batteries/2084/2) for more information.

If you choose to go ahead with the above-rated-voltage battery without using a regulator, there’s information [here](https://discuss.bluerobotics.com/t/raspberry-and-pixhawk-shutdown-problem/10814/2) that can help you set a hard limit on the commands sent to the ESCs, to reduce the chances of the thrusters getting damaged.

EDIT: I’ve just seen in [your other post](https://discuss.bluerobotics.com/t/t200-current-draw-and-choosing-a-suitable-battery/11387) that you’re making a boat, so may not be using ArduSub to control it. If that’s the case then the same principal applies for limiting the PWM signals that get sent to the ESC, but you would need to set that up yourself for the system you’re using.
