Hmmm. Didn't run across that one but that wasn't my problem anyway.
But I did find the exact thermal fuse for the battery box. Ended up getting it straight from the manufacturer. Couldn't get just one had to get a bunch (20) so if anyone in the US needs one quick I'd be glad to help them out.
Mine has a different thermal fuse in it.

But have been unable to locate one anywhere. Been looking for two days.
Finally found some in China that appear to have the exact specs but I would rather use the OEM part.
Can you tell me where you got yours?
I'm in the US...
