If you had flooded batteries you could put 80amps into them during bulk charging (20% of capacity).
With AGM's...you could easily put 160amps into them thus cutting your charging time in half...BUT on the hook you need a 160a charger working off a generator or a 160a alternator that can give that much output in order to realize that benefit. Either way, you need a 3stage charger or regulator along with the additional capacity.
That's why I said charging system rather than just one component of the system.

Cam, thank you for that explanation.
