While about a mile from home yesterday the display on my yosepower rear hub went dead, when I opened the battery this is what I found

What is likely to have caused the problem?

High current being drawn through a poor/bad/corroded electrical contact creates heat that melts the plastic.

Thanks for the prompt reply cyclebuddy,
is this repairable or should I just replace the battery? It’s just two years old.
