    Skooch has 880 AH of Lifeline AGMs. But only one year of real use. I got the
    AGMs because on the Hatteras the batteries are on the outside of the motors
    on the stb side in two layers. Nearly impossible to check unless your a
    monkey. I may act like a monkey but I can't reach these batteries, not with
    a mirror, not with a watering wand. So economics did not come into play.

    They charge at 100-125 amps from the SW2512 inverter (depends on the heat).
    The best I've seen from the 150 amp alternator is 75 amps of charging. I
    need to check the settings on the regulator, but I rarely need more than
    that because I need about 250 amp hours after a day at anchor which is >4
    hours of run time. Note: I have to run the gen set to cook . . . so when I
    get a hot meal (not including coffee or microwave stuff) the batteries get
    100 amps of charge for however time the dinner-lunch-breakfast takes. And if
    its one of those hot humid nights on the Bay (not many this year), well the
    A/C is running and everything is re-charged.
