By "terminal rubber insulation" do you mean the insulation on the lugs that bolt to the terminals on the batteries? If so, this is a sign that you either didn't clean the contacts or didn't bolt them together firmly. Those batteries need to be initially charged, and they draw a lot of current when doing that... which heats up any kind of high resistance connection in the chain.

Any ideas to the cause?  The status screens looked ok. ("no bad
batteries" again)

By the way, you probably ought to replace all the batteries in all your packs regardless of what the battery status monitor says.


Yeah my other thought here was that one or more of the other packs had totally dead shorted cells, that'd cause excessive heating on the other batteries too.
