Small Battery Instead of Large Deep-Cycle
My trailer is always connected either to shore power, or to my truck. Even at home where I store it. I never boondock and have no plans to do so. I'm thinking of buying a smaller, cheaper, battery...

I can see where the OP may want to do this if he wants to reduce weight.
A small 12 volt lawnmower battery at Wallyworld is 18 pounds and costs about $20. Whether that has enough reserve to power break-away brakes or not, I don't know. I would assume that it does because those brakes only need to hold for the short time the trailer is free until it comes to a stop. But I am not knowledgeable in how much juice this would take. If you are doing a lot of mountain travelling, probably not a good idea. But maybe a possibility if you travel mostly in flat terrain.
