Agree with YO, Surge and Q3. Most circuit breakers have a voltage drop.
My recommendation is:

Or 4008 if you want more circuits.
It'll be tidy and inside the panel. You can't replace a fuse in flight but probably shouldn't.
A side benefit of using 15A PowerPoles for everything is that you can connect any instrument to a battery on the bench if necessary.
