Has anyone have any information about what wire to use as a fuse wire? I’m building a 20S30P battery pack from old recycled laptop batteries, so I decided to use a tesla style fuse. I can’t find any fuse wire in Indonesia, is there any wire that I can use as an alternative? I’m looking for a fuse wire that will blow around 6 to 8 amp.

Any help is appreciated.
 
Check out the table here: https://en.wikipedia.org/wiki/American_wire_gauge

It has some columns that tell you the fusing current for various sizes of copper wire.

I bought some tinned 30 AWG wire for this purpose. Used it to make a battery pack a couple years ago for a portable TV. Just recently I took out the battery to check on it and found that one of the parallel connections I had done with the fuse wire had broken off. This might have been due to the crappy microwave transformer spot welder that I had back then. Maybe a better spot welder would make more reliable welds.
