They replied to my comment saying they're going to change them, which is a good thing. Once they do I'll amend my post above.
bobc: For the 11A rating, there are NO PTC fuses available from Bourns that have a rating greater than 16V, which is the whole problem - they simply don't go that high. And you can't run them in parallel or series easily to share the current or voltage rating, due to the way they work internally.
