Max AGM charging Amps

Hey all -
Trying to understand what / how I should be charging my 12V 600Ah bank of batteries in my RV. I want to make sure that I don't cook the batteries or not get them enough charge.

3 200Ah 12V AGM batteries wired in parallel.
They started the the morning between 12.3V and 12.4V and now charging away in bulk @ 13.6V at about 64A. Mfg specs say to absorb between 14.5 and 15V and then float @ 13.5 to 13.8V

What I want to know or how to figure out is how to properly calculate how much amperage I should throw at the batteries or is there a limit I will hit ?
Thanks
Thanks

Enough charge is mostly a matter of absorb termination criteria and absorb time.
