If you have a brake away system fitted to the trailer it will have a battery fitted and it will need to be charged. This battery is only used for the brake system so you can charge it from the aux pin in the trailer plug. you then fit the Anderson plug to charge your trailer battery.
You only need a brake away system if the trailer weights over 2 ton.
Hope this helps. Also check out Brake safe on the net as they make the system
