Sunny side up please.
DIY Gents?

Fuse both Pos and Neg wires?
Ya, but I was commenting on the video. Just wondering why he did that.Just Pos.
A metal box to contain any fireball would be good. Vents or other cooling could help avoid nuisance blowing on a hot day. (competing goals.)
Other type fuses are dual element, blow faster with extreme overload and hold longer with sort-term modest overload.
cost?
max voltage 32v, no good for 48v .$44, vs. $11

True, the fuse is a given. The strange part is the $4x dollar block of plastic that holds the fuse. It's just plastic with 2 nuts in it? That's the part I'm questioning DIYing.If you can afford a 48V battery, you can afford a $44 fuse.
yes, that's were the class T fuse comes in and again, the holder.MRBF is 58V for $18. But only 2000 AIC

I appreciate some of the benefits that gives you, but why did you choose that approach? Are you concerned about ground faults?I have all 10 of my 16S 280aH batteries with 125A JJN Class T fuses, mounted using two standard bus bars with ss hardware, between cell 8+ and Cell 9-. Wrapped in Polyamide tape. Typ max current= 37A. I've test blown one fuse. A little pop. That's it. Now you have two 24V batteries.

I thought there was a reason that approach isn't encouraged, but I can't think of why. I know mid-string disconnects are common, but fusing is a little different.
Typ max current= 37A.
Best strategy as far as I can tell, in these times of shortage, it to buy the holder and fuse together, and several spares to fit the holder. All at once. T fuses of a particular size are a pain to find these days.
