Hello everyone, I am new to this hobby and I am using T200 thruster with commander but I will be using 20v power supply to drive this kit, I have question in regards to commander, do I need to buy separate step down convertor from 20v to 5 v to power up the commander or I can feed the power from same 20v power supply? Thank you, Rav ---

thank you so much, when I heard 5v in the video on webpage, I got confused on if I should be feeding the commander only 5v. But thank you for clarification, how these thrusters hold in saltwater? Rav ---
