I actually do use the same kind of fuse for the charge port:
Why not? Fused loop key makes a lot of sense to me. If it blows, it’s easy to replace. When testing, I can carry another loop key in my pocket and not have to push home in case the test doesn’t work out as expected.
I have 50A current limit on each motor. I’m going to add 30A battery limit per VESC as well so that I don’t exceed 60A battery limit total, though I don’t really ever do.
60A for a few secs should be perfectly safe. There’s padding. Even at 2x rated current the fuse should take a few seconds to blow (according to the data sheet).
I’m thinking of putting on all my protective gear and doing some uphill runs with hard acceleration. Maybe carry the board downhill until I have enough confidence the fuses don’t blow under hard braking current.
