The standard battery size for a breakaway system is 5 amp hours. I recommend the Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger part # 20400 which is a complete kit that has everything you need. It also have a cool feature where you can simply press a button to see if your battery is charged and ready to go. It comes with the battery, switch, and mounting box.
