I'm headed that way. From reading this thread over last 2 days, I have a lot of work to do! I plan to make room for metal box over both fuse and contactor for both batteries. That area is tight and gets to 85f while room is 78f. Top of Sol-Ark is 95f. Hottest point anywhere is Shunt bolt @ 90f.

All your individual fuses are a great safety from cell shorting out.
I agree with UN&P that fuse needs a holder.

OK, so no claim that 12V or whatever can jump 1/8".
That was the original disagreement we were discussing - whether a screwdriver could draw an arc from a 12V car battery without having ever come in contact.
Guilty as charged. But my welder is an AC buzz box, a 3:1 step-down transformer with movable core.
Is there anything I can do which is better than dragging the flux-coated stick across my workpiece?
That's not what a semiconductor fuse is though. A semiconductor fuse is named as such because it's designed to protect electronic equipment (such as inverters). They're essentially really fast fuses, but don't contain electronics themselves.

I don't believe a Semiconductor fuse is a circuit made from semiconductors.
Just fast fuse material.

A semiconductor fuse is a fast-acting, compact protective device designed to safeguard sensitive electronic components from overcurrents and short circuits.

If corn oil is made from corn...I don't believe a Semiconductor fuse is a circuit made from semiconductors.

Thanks for the correction - I have learned my one new thing for the day and need to go back to bed before I learn anything else.If corn oil is made from corn...

For everyone else here is the link to how they work and page 8 has some good info. And the quenching material is sifted quartz, so quartz sand verse straight silica sand, i.e. both are silicone dioxide but quartz has a little bit of impurity and it and is cheaper.
High speed fuses are primarily for protecting semiconductors fromshort-circuits. Their high operating temperatures often restrict usingelement alloys with a lower melting temperature to assist with overloadoperation. The result is that high speed fuses are generally not “fullrange” (operate on short-circuit and overload conditions) and have morelimited capability to protect against low-level overcurrent conditions
OH NO! I learned something else, I may have faint from shock.
This concerns bus bars - for longer bus bars it is better to go thicker than wider.

absolutely clean surface, rust free, paint and corrosion free, if you are using standard US rods say 60xx 10, 11, 13 or any of the 70xx series match the thickness of the rods to what you are welding.
Too many folks just grab whatever is available and are normally welding on material with the wrong size rods. required amps change with rod diameter and do you really need to be welding with a 1/8 rod? I mean if you are welding something thicker than 10mm Ok...
change from scratch to tap. then after practicing a bit you will notice that if the rod is new, the surface is clean right before the rod contacts the surface an arc will start to form... practice until you can stop the tip right at that point without actually touching the surface. practice makes perfect. I only weld on less than 10% of the various contracts I bid on, but the navy is spasmodically anal about welds. leave it at that.

The only two things probably more critical and anal would be doing hot taps on gas lines and cooling lines for nuclear reactors.
Not sure, but this is the link: https://www.amazon.com/dp/B0BQZ83SVM?ref=ppx_yo2ov_dt_b_product_details&th=1

Interesting first review on that page.....

I was wrong, those are fine other than not being mounted in a fuse holder.

That is clearly a Class T fuse.

From my link above - I've seen various questions about fuses used in parallel.

Stated 3.45 v as seen and read. It stopped my runner The victron treats these cells as if brand new. The UL1974 basically talks about repurposing cell from auto and such. But it is a requirement to be UL compliant. Guess they-govt don’t want ppl buying new cells.
The voltage was addressed. Ppl can do as they wish. What comes comes results often prove points. Why this particular Up in Smoke forum exists….. Cheech and Chong movie

dont think it can melt because lfp does not burn hot enough. different story with nmc or lipo
but if the shelf is out of thin metal with no insulation it can collapse because hot steel is not stable enough.
