Couple of questions about DC-Dc charging
I've been thinking about adding a DC-DC charger now that I've added 400 amp hours of AGM batteries. There are lots of useful posts but I haven't run into a couple of things I'm curious about. One ...

Thanks everyone for your responses. So to summarize: My object here with the DC-DC charger is to properly charge my batteries but limit the amperage as to not burn out my alternator. It sounds like my 130 amp alternator may be at the low end of what is needed to really handle 40+ amps of charging for possible hours on end of normal driving. I'm not adverse to upgrading the alternator for a higher amp, or really, a heavier build that can handle the constant current needed to charge the (4) 100amp at possible 50% state of charge.
As to the solenoid that is currently separating the chassis and starter batteries. It should be disconnected and I will extend the wire that energizes that solenoid as the D+ wire for the DC-DC charger.
Does that sound about right? Any other suggestions of real world experience would be greatly appreciated.
