Magic smoke! What happened to the JK-BMS? Still reliable or bad design?

Описание: After we saw some magic smoke from the JK-BMS in the last video (   • The JK-BMS 4S-8S Edition - World Premiere....  ), we want to find out what exactly happened and why the BMS exploded... but still works.
After pulling just over 200A for only 5 min, one of the MOSFETs died when the BMS disconnected the current. What a scary moment! I really thought, that this is the end of the BMS!
But hey, it is still working fine and nothing obvious happened. So let's open it up, sniff a bit around and see if we can find any suspicious stuff!

Can the JK-BMS be saved?
