X2 on that.
If you have trailer brakes, they must be capable of operating independently, in the event of a breakaway. (The way it was explained to me, "This means the trailer will safely come to a halt in the middle of the interstate, while you make your getaway " :-)
If you have electric brakes, that means a battery.
I'm pretty sure that's a legal requirement in most places and, more importantly, it's a safety consideration.
If you don't have the right battery, then you can use a regular car battery as a temporary measure. if you can secure it in your battery box.
