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 ...

What wire size feeds the AGMs?
The wire feeding the house batteries, 200 amphrs, appears to be 2 gauge. I would assume it would be capable of delivering as much current as the alternator can deliver, safely. The second bank comes off the house batteries using 4 gauge and can be separated, and used independently from the house batteries. This second bank is also directly connected to my inverter. My intent was to get the Renogy 40 amp charger which I believe the wires can easily support but can the alternator?
How much current are you getting from the alternator with the existing set up?
Last I checked it was putting out 119 amps at 14.4 volts. I was lowering my jacks to put on a load. It may put out more.
