Aha so I just need to solder on a new fuse holder, and then plug in a new fuse in to that new fuse holder? Any idea on what these are called, on for example Aiexpress? Just "fuse holder" with fuse or something perhaps?
Correct, just "fuse holder" will work, "inline fuse holder" might get slightly better returns.

The post you are referring to is the post above perhaps? Thanks
Correct... "You will find the post linked below very helpful, lots of great info about fuses and the this specific issue, especially towards the bottom of the page.

By the way could any of you tell me what the difference in function is between a fuse and a bms? Do they both perform some kind of heat-protection of the battery cells or something like that? And if so, what is the difference between them?
A fuse protects against going over the rated amperage, which can cause electrical fires. A BMS stands for Battery Management System, and it makes sure the cells are charged evenly and correctly, without it the battery might not get charged properly, which could reduce efficiency, battery life, and also cause the battery to explode or catch fire.

Do you think it would be enough to buy a fuse holder like this picture below? It is rated at a max current of 30Ah. My battery is 36v 13ah.
The one in the picture will work, but is very similar to the one that melted on you already, so there is a chance you will run into the same problem the next time you're powering hard up a hill, because that is when the motor is going to draw high amperage.

The actual fuse that I put into the fuse holder should also have 30ah then? Or lower?
The actual fuse that you put into the fuse holder should match (exactly) the amp rating of the fuse that was in there originally. Hopefully you can still read that on the top of the fuse.
Mine is 30 amps, but not all batteries are the same. Side note, fuses are rated by amps, not amp hours, so you will not find a fuse labeled 30ah, it will be 30a. Do not assume your battery is rated at 30 amps because it is a 36 volt battery though, the two numbers have nothing to do with each other.

I could basically cut off the two red wires and solder them onto the new fuse holder, right?
Correct, including the smaller red wire I previously though wasn't going to the fuse, but I see now that it is.
