I'm pretty new to boats even though I've been flying nitro RC for 15+ years, but electric boats are different. I got a good motor, ESC, and hookup for twin batteries in a Lobster Boat I'm putting together, but my question is do I need to insert a fuse in the circuit? I used to race rc cars with my sons many years ago and I remember a fuse being inserted and every once in awhile it need to be replaced. Do I need a fuse for boat use, and if so, where does it go in circuit? Thanks....
