I think you've convinced me to install a fuse!
New high-current fuses are expensive. But I have a decent collection of surplus fuses. Here are some examples. Note that AC rated fuses should only be used up to 1/4 of that voltage on DC. Write me off-list if you'd like one.

I was sorta hoping that the controller (Curtis 1231C-8601) had some sort of over-current protection, but that won't protect against a mechanical short between the pack and the controller.
No, it doesn't. Without an input fuse, it explodes in a fiery burst of debris if anything inside fails shorted.
At best, [conservation] means we will run out of energy a little more slowly. -- Ronald Reagan
Conservation is important because it gives us *time* to look for other options. It's a "second chance", to do it better the next time.
But, second chances are only valuable if we change our behavior. We need to stop doing what got us into the situation in the first place.
