a few quick questions for all you
bright sparks out there.
Im going to fit dual batterys to my camper trailer,im looking at buying 2x 120amp fullriver batterys, they will be charged off the 4wd when on the move, and be charged off maybe a CTEK multi xs7000 charger when near 240 volt.
The questions that i have is il be running a engel 60ltr combi, and are wanting to know how long i would get out of the batterys running the engel(with it being only opened late in the arvo's) and if what im looking at getting is overkill or should i look at some other set up.(bigger amp batterys)
also is the charger going to be big enough to charge the batterys or should i look at buying the xs25000 charger.
Im hoping to get around 3-4 days from the batterys, am i dreaming?
thanks all.

I've read some of the responses and fair dinkhum, some people don't understand electrics.
Proviso 1. If you ever hope to get some life out of your AGM batteries, NEVER discharge them below 50% of their capacity. Hence you have 110 amps available. I personally prefer to discharge them less than that.
Given you have 110 amps available; the Engel will draw about 50 during an "average" day, say mid 20's. In summer, on a hot day, it could draw as much as 100 amps. In the guts of winter you may only draw 30, but it would be a bloody cold trip.
In essence on a trip in Autumn weather, two days would be the max before you start hurting the battery.
Solar, or a gennie and decent battery charger is the way to go. You can of course run your engine to help charge via the alternator. It's a very effective "generator".
