JK-BMS B2A8S20P (11.2 version) temperature 86.3°C (187.34°F) too high ?

The cell temps stay a cool 32 deg C.hence why i suspect the issue may have to do with how i extended the P cable .
I only added a 7inch extension using 35mm cable to the P cable and nothing to the B cable. Could this be an issue?

If it's a poor connection with the extension, then that could be the problem. I would expect the wires to be hot too.

As he said only a problem if it is a bad crimp or you are using alu cable...
