The 7355 in ours is 10 years old and still going strong. Great converter for when on shore power, but a slow battery charger due to the 13.8v and a long wire.
There is no charging circuit; the batts are just exposed to the 13.8 and you get whatever current the "spread" allows between batt voltage and 13.8--ie not much.
To get full current from the 7355 you can run it as a supply to batteries that are on an inverter which is running a big load. I ran a test of that where the inverter was drawing 90a from the batts as seen on the Trimetric. Used the 7355 with short fat wires to the batts and Trimetric showed minus 34a instead of minus 90a. This shows the 7355 was doing 56a. In its normal location on longer fat wire, with normal battery charging, I see 35 to 40a at most that tapers quickly.
For fast charging to keep gen time down I use higher amp, higher voltage chargers. (Phil, lots of them will do constant amps in bulk while the batts will accept them. PowerMax, Vector/B&D, Paramode, WFCO, Iota all will.

Yes. Voltage goes up as load is drawn. As per original post with battery's fuse in i may start somewhere in the 12.4 range depending in the battery state at the time.
If I turn on 3 or 4 lights, I can hear the 7345 come to life and voltage will increase to just over 13vdc. If I turn on everything 12v in the coach I can get the voltage as high as 13.8.
The 7345 works, aside from the charging portion, it simply does not see the battery as a load. You would expect most to loose voltage as their max current is reached. And i'm sure this would as wellI, i just can't draw that much off of it.
