MIDI fuse, need longer ones

i have a need for 50a midi fuses, like this


but, what i am doing requires the length to be 2.5" center to center between the mounting holes. i searched around, it seems all are much shorter, nobody makes one in that length.

thought to solder an piece of copper to one of the ends, but in fear that the fuse could be melted during soldering... will solid rivet do the job? (5/16" hole though).

any idea?

CountryFit-

I suspect you need a different fuse design. Among the helpful reference material available at this Blue Sea Systems link is this fuse chart. I also like their wire size, fuse and fuse holder selection chart, at this link.

thanks both of you! i just called digikey and allied electronics, what they all have are the shorter ones. digikey said they can custom order for me, but require minimum 500 pcs and 7 weeks turn around...

in my application, other fuse types won't fit the space well.

Hmmm. I find that when I'm dealing with a safety device, such as a fuse, it pays to use standard components. If you must have approximately 2.5 inches center-to-center, consider the ANL fuse. Here's a link to a dimensioned drawing, a link to a Blue Sea 50A ANL fuse, and a link to their matching fuse holders. The MSRP on the fuse is $19.99.

What was there?

If you have a real fuse holder and no fuse then need to find correct fuse.

If making something make it correct size.

among 4 li cells in series, if one goes kaput, its resistance will become 0 (not a typo). the other 3 in the series will suffer from the high current flow through, eventually one by one they all will go to the same destination. in that case, the line is essentially being "shorted", causing all neighboring cells in series then paralleled with this "shorted" line to overheat thus to create a fire.

if one has bms and it works as designed, no problem, the bms will take care of it. but i have heard more than once the bms failed to act. for me, i don't use bms but use just a balancer.

in the past 1.5 years, i have been using this for each group of 4 cells in series:

considering 13 groups, that is a lot of wires.

now i'd like to place a midi or anl fuse in each group without using above block. mark's link is promising though pricey . if a dead cell ever happens, the fuse will be burned, safe for the whole system. make sense at all?

Cool.

There are many sources of aftermarket wiring supplies where these things can be reviewed and ordered.

We use a place in Fresno called mid term supply for last 30 plus years for automotive stuff.

They have lots of interesting things as does digital key.

They are a small operation and owner is sharp and does work the phone.

It could be McGyvered a little. Take a 12 volt battery lug, squeeze the round cable opening in a vice until it starts to flatten out. Slide one end of your fuse in the opening and then completely crimp the end onto the fuse. Obviously, you would need to see if the lug and fuse together meet your length requirement. You could even drive a rivet through the two where they connect.

To prevent the soldering heat from potentially damaging the fuse, before soldering, grasp the tab, up against the fuse body, with a pair of long nose pliers. The pliers will act as a heat sink and the soldering heat will not get past the pliers into the fuse body.

If you don't have a helper to hold the pliers, use a rubber band around the handles.

what an idea . if i can find a right size lug and flatten it with a mallet while the fuse is in, it should work.
