Hi Cor,
Have you verified your cables don't have high resistance? I'd check
post-post and lug-lug resistances across all your battery cables. While
the hard bump could well have caused internal damage to one or more
batteries, it would be a good idea to check top-side also.
If you haven't already repaired the battery, if it is in fact
repairable, since I believe you live in an apt., it's probably just
simplest to give Jim Ramos @ American Battery a call and arrange for him
to recast the post. I have some recollection he will do that.

Hi Scott,
No problem - indeed an automotive (round) style post.
The week before it melted, I hit a particular hard bump
with the truck, so I have some suspicion that the batteries
may have moved from that bump and either the post was damaged
(maybe sheared partially off) or the clamp was never tight
enough so it moved, crud or corrosion cause bad contact
and the resistance heated the post until it melted.
The last few days before this happening I was asking
myself why the charge meter was dropping so fast in the
first mile driven, going down 10% within 1 mile, as if the
pack was losing charge or dropped in voltage, but it was not
cold weather. Now I know that it was the high resistance link!
Next time I will be more in tune with the signs that say
that something is amiss in the pack...
