The way I built my compression frame, it extends well above the height of the terminals. Anything I place over the batteries will rest on the frame, not the terminals/cables/lugs.
I am thinking the alternate layout is much more likely to have a major short.

If you don't mind my asking, why do you feel its safer?I'm thinking about switching to the original layout. It seems safer to me.
And it will be easier to make a flip open cover
If I short the original configuration less cells are involved. It's almost impossible to short all cells on the original layout.If you don't mind my asking, why do you feel its safer?
Is there something specific that you are avoiding?
I'm going to do a little table top research. Someone mentioned that electric wire insulation burns. I found that counter intuitive so I tried and indeed it does. So long as there is a flame it burns. Remove the flame and it goes out. Same with the insulators on terminal crimps. 2 types of heat shrink I've tried so far went on burning without an external flame. I'm gathering up every kind of material I can find around the homestead and will post results eventually. Meanwhile anyone heard of Starlite? Or intumescent paint? There's some far out materials I want to try set fire to.Don't put plywood or cardboard over the batteries. I have to go out and remove mine.
Fire!! Never cover LiFePO4 with wood!!!
New adventure.. I went inside the battery room. As the exhaust fans where working, and they are temp based, I felt OK to close the door. I used wood (MDF) to cover the cells and sit on top, and to prevent accident if something falls 2 left over pieces, 10mm, but strong enough to sit on, as...diysolarforum.com
I think that's what is meant by "self-extinguishing" vs "non-flammable"?I'm going to do a little table top research. Someone mentioned that electric wire insulation burns.

Never worn a helmet and I have cycle toured Europe. Only wear a seat belt when I think there might be a cop in the bushes.
It's interesting to think things through. Not so interesting to let Google do it for you. I sometimes get diametrically opposite answers. Anyway, one does ones best and then lets go. If you want your boomerang to come back first you have to throw it.I wonder about the plastic cover on these fuse holders - https://www.bluesea.com/products/5007100/Class_T_Fuse_Block_with_Insulating_Cover_-_110_to_200A
It says-
Eventually I'll break off a piece and try to light it on fire
- Insulating cover satisfies ABYC/USCG insulation requirements
- UL 94-V0 base resists high heat
There is another thing I am trying to avoid. Arcs.If you don't mind my asking, why do you feel its safer?

I've been down a dozen times. One time over the bars down a flight of stairs on a mountain bike. My feeling is that what you can't risk losing is not worth having. Just me setting a bad example. Not giving advice.I've never met anyone who had been killed by not wearing a seatbelt.
But I have seen many cars with punched windshields.
Similar for helmets; one of mine has some nice circular patterns in the paint.

Not DOT or SNELL? Say it weren't so.I got knocked off a motorcycle going 70 mph. If I didn't have on a cheap novelty helmet I'd have a flat spot worn into my scull just like the one on the helmet.
I think I did stick a DOT sticker on it. We're way off topicNot DOT or SNELL? Say it weren't so.
Yep. Become DIY philosophy. Let's try to focus. (Largely my fault I think. Sorry.)I think I did stick a DOT sticker on it. We're way off topic
There's insufficient information. It's rated to 250Vdc but you're right -- the breaking capacity isn't qualified with AC or DC. It looks like it's mostly designed for an AC circuit so I personally wouldn't choose it.I know I'm a bit late to join this discussion, but am hoping for a sanity check on a fuse I want to use.
I need a fuse that is somewhere between my max load of about 130A and the max current rating of my cables, 188A. It could potentially see the full force of a 450Ah 8s LiFePO4, so I think I want a high interrupt rating. Class T fuses below 225A are a real hassle to obtain in Australia, and expensive.
My reading of the specifications seems to indicate this NH fuse will work. I'm a bit unclear whether the "Rated breaking capacity: 120kA" on page 1 of the data sheet applies to DC or just AC. Details for the 160A version are on page 3.

Data sheet
I'd really appreciate if anyone can help me decipher the data sheet.
