Something I haven't seen but would like to mention. Do not move the trailer with the trailer battery dead! If, God forbid, your trailer were to break lose the electric breaks will not work. They need thhe trailer battery to work when the emergency cable release is pulled. Once your trailer becomes disconnected from your TV the only power the brakes would have would come from the trailer battery.
It is not worth the chance, charge the battery before going anywhere.
