High current fuses?

[TechAUmNu]

What fuses are people using for their heavyweights?

I need a 200A for 8S and a 400A for 12S.

Highest voltage rating fuses I can find at 400A are these:

I guess I could just use two of the 200A in parallel for the 400A, then I only need one rating of fuse.

I don't really trust that for 50+V. Got these instead.
