How can i replace that thing?

Find out what caused the fuse to blow. Fix that.
Disassemble the battery and remove the old fuse.
" Procure one of the same type and rating and replace"
Charge outside your house and away from anything flammable.

there is no rating, brand nor anything to know the fuse specs,
the fuse is a pice of metal that melted, the silkscreen on the pcb said FUSE beside the melted plate fuse, and thats the main problem.

also it thick with solder at the side removing it would be dangerous as you cant pass heat to the cells underneat the pcb.

but knowing the raiting of that fuse would allow me to put a fuse in the place of the plate, restoring function and ensuring safe operation of the battery..

ryobi does not list the wattage of any of their cordless devices so calculating the max intended current output is imposible.
