Fuse box upgrade

Would running the keyed on through a relay help things? The leash box has the ignition side run through a relay first. That’s a good price using two. I need to see what is battery hot and keyed

Relays are always a good thing. Supposedly it can handle the amperage, but Chinese amps are calculated differently.

And to be clear, I use this for aftermarket. Fans, stereo, upgraded lighting, air conditioner, backup cam, etc.
