Homebuilt ROVs Forum

Has anyone thought about fuses for their rov systems, like blade fuses or auto resets?

Fuses are very important. You can fuse components individually, but make sure you have a master fuse as close to the battery as possible.

What sizes would you suggest for things like the motors, or the entire system?

It's really going to depend on the current your motors draw. If you have an amp meter you can measure how much current individual components of your ROV use, and add them up to get your maximum overall current draw. Then use a fuse with a bit of safety margin.
