BMS balance wires with 10K resistors and solder blob...what is this?

Post by newb123 » Jun 08 2019 7:24am

During a Li-on pack disassembly I found that the balance wires to the cells had shrink tube covering solder blobs then a thin wire from that to a 10K resistor (see pic) Just wondering what the 10K is for; I can understand the thin wire and solder blob might be a fuse of sorts, but why the 10K?
