LIB48 W205 - Fuse in BMS

[Filu02]

Can anyone tell me what model and type of fuse I need?
Mine are overheating and I don't see any markings on them.

Are you sure the fuse is the problem? If you select a fuse with the same rating, then, according to Joule's law, they will heat up equally. However, if you have to use a fuse with a higher current rating to prevent overheating, this indicates a fault somewhere in the circuit causing excessive current draw.

One of the fuses is blown, and another one seems to be overheating. So I tried replacing them all with new ones, but I don't know the model or the required wattage.

I searched online and found a better photo of the components you mentioned. It turns out they're not fuses, but shunt resistors with a nominal resistance of 0.050 Ohms and a tolerance of 5% (J). It's logical that when one of them burned out, the others began to heat up, because the current that previously flowed through that resistor was now distributed among the remaining six.

You're absolutely right.
I ordered this model (OARS1R050JLF), they're very similar.
Thank you very much.
