Correct - fastblow 4A.

If you have any capacitive load (often some technically competent club
member puts a largish capacitor in to make sure power isn't interrupted
when switching batteries) then slow blow is a better option. The main
purpose of fuses is to protect the wiring, and slow blow will fulfil that
requirement.

That would almost certainly be fast blow 4 amp/250 volts.
