I am investigating the use of an OpenROV for short range operation in gardened lakes. The operational range would be less then 25 meters. For this application I am thinking about a wired energy supply to get rid of the batteries and the charge process (and maybe replace them with a technical equipment!).
What specification do i need to meet here? My first approach would be to solder the two wires from the tubes to a two wire connection to an ordinary power supply unit, that matches the batteries voltage output and is able to supply enough Current. Anything else? Any advice for a cable/wire?
Thanks a lot for your help!
