Robô Aspirador Liectroux XR500, igual ao Smart 700 da Kabum, bateria com problema

This robot vacuum cleaner has a battery problem. It's a Liectroux XR500 model, which is the same as the Smart 700 from Kabum, and the battery seems to be the same as the Smart 500 as well. The problem is with the D6SC4-12 fuse on the BMS board. I bought three parts on AliExpress. The tricky part is the soldering; you have to solder very quickly, either with a hot air gun or a soldering iron. Be careful not to lose the fuse during soldering, as it's very sensitive to heat.
