Battery Charger Fuses

[Dragonten]

I just installed a new 32 volt Sterling battery charger in the boat. The old charger does not appear to have any fuses at least that I am seeing. None on the engine batteries. Are there fuses somewhere else or should I be installing some? The charger puts out 20 amps at 36 volts my understanding is a 25 amp fuse is recommended just not sure of voltage either. If I need fuses does anyone have a recommendation? I was looking at Bluesea stud fuses but they only seem to come in 30 amps. Engine starting amps need to be accounted for I suspect.

Thanks,

Mark

May I recommend a breaker.
