If you have a break away kit that does not include a charger, you can provide a charge to the battery using the 12 volt circuit or auxiliary circuit from the vehicle 7-Way trailer connector. However, using the 7-Way can overcharge a break away battery. It would better to add a charger designed for a break away battery like # 20011.
