We are trying to implement a surface power supply for our BlueROV2.

What is the maximum and minimum input voltage range of the input voltage, in order to rate properly our power supply?

Hi @manci -  
The 5V power supply in the BlueROV2 main electronics has a minimum voltage of 7, and the PSM module a maximum voltage of 25.2. The BasicESC works with 2 to 6S batteries, so I think 7-25.2 V is a safe input range for the system.  
The T200 however is only rated for 7-20V, if using above 20V it’s a good idea to limit the maximum throttle to keep the power consumption per thruster at less than ~700 watts.
