    Hello,
    I understand that I need a battery for the emergency braking system if the trailer disconnects from my tow vehicle. Other than that however why do I need a battery if I don’t dry camp/boondock??
    Pls let me know.
    Thx,
    Q

    If you're going to camp exclusively at camprounds with electrical hookups, you can get by without a battery, your converter will supply the 12v necessary for lights, etc, your outlets will of course be supplied by shore power.

    All you need for the electric brake breakaway switch is a small 12 volt battery like for a lawn mower or emergency exit sign.

    No Batteries Required for camping if you dont want them.

    If thhere are any 12v loads that exceed your converter's capacity, you would need a battery to provide coverage for that load. A roof lift winch could possibly fit that description.

    So when you arrive at a campground and they tell you they do not have any sites with elec - or your power pedestal goes out - you will not be in the dark. ;)

    You could also have a flashlight, lantern or a candle.

    I would assume if you use the fridge (3 way) you can run your fridge on DC while driving to the site, then switch to shore power upon setting up at the site.

    I have not had one since I bought mine. I camp exclusively at state parks with electric/water hookups. I don't have electric brakes so there is no worry there. I'll probably have one on a TT if I get one simply because there may be a time when I have to overnight in a parking lot or at a non electric site on the way to my destination.

    Do you have a manual crank up winch or power winch?

    Depending on your converter, you may need a battery to "close the circuit" regardless of being hooked up to shore power or not.

    i Leave it hooked up, no need to disconnect it. At least on my camper being on shore power can actually charge the battery.

    Okay. But what do you mean by closing the circuit?

    I just mean that without a battery, the electricity can't reach the final destination (lights, water pump, etc.). Not all systems/converters work that way, but some do.

    Gotcha! Well just take that nicely charged battery with us. We usually dry camp so this will be the first time at a full service site for a couple days.

    I've never seen any such wiring in 20 yrs of RVing and certainly in your case with a 2000 Niagara it wouldn't apply anyway, no more than was the case with my 2000 Santa Fe on which I didn't have any battery for the first 5 yrs we owned that trailer. The only reason for having a battery is so the trailer brakes breakaway system will function and of course a battery will serve as a source of back up 12 vdc power should you lose campsite shore power for some reason.

    Never saw a convertor that works this way. Current will go from the convertor to the various loads,,,and the battery. Not through the battery then to the loads

    Certainly not true with the OP's 2000 Niagara. First, she made no mention of a power lift and second, if this particular unit did have one plugging the trailer into shore power while using the power lift is a NO-NO as doing so can destroy the lift system's current limiter. [:(!]

    We do slideouts and roofs daily with only shore power, no battery, without any problems
