Expert Reply:

The part # 20011 that you referenced is designed to charge a breakaway battery (which is very small). It sounds like you are looking for something to put a maintenance charge on a larger battery.

Which if so you would instead want to run a length of 10 gauge wire like part # 10-1-1 from the 12 volt accessory circuit of your trailer wiring to the positive battery post. A thicker gauge wire will do a much better job charging a battery as opposed to the thinner wires of the # 20011.
