Updated 31 Jan 17 Initial results. I will re-test the AGM after it does one deep cycle to confirm these results. EDIT completed 6 Oct Test was to put the test battery as the only battery run...

My problem here is not the need for fast charging from the gen so that I would like to use higher than spec amps. The recharge would be on shore power, time not an issue. I don't mind the 30% limit as such.
The problem is the 55 amp converter that cannot be limited in its amps. It makes a great Float charger with the adjustable voltage, and since the batt is full while floating , amps are low anyway.
When the power comes back on and the batt has run down while the power was off, now the converter comes back on and does its full amps, no stopping it.
If there is no harm to the battery from getting that 55 instead of 27 amps, it is not an issue. If there is harm from that, then in theory I would have to use a 25 amp converter or else get a second battery to bank them so the 55 amps is shared 27.5 each.
Or I could not use the converter at all when on shore power for the weekend and just run the batts down till home again. Or I could use my 2 amp charger as the converter for when away. it would help a little bit after the power came back on, sort of.
Most of the DC draw in the Truck Camper is from the inverter running 120v stuff Eg the furnace is a gravity type with no DC fan. so I don't need a higher amp converter to run the rig's DC while on shore power.
I just want to know (whine) if it is safe to leave the 55 amp converter in there for weekends on shore power when there might be a temporary power failure, as often happens. If it is harmful, I won't. Argghh :(
