Blue Ox Towed Vehicle Charge Lines

The Blue Ox towed vehicle charge lines are designed for maintaining your towed vehicle's battery while flat towing behind your RV. This is especially important for modern vehicles which can have a significant draw on the battery, even when not being actively driven. These battery charger accessories can help to prevent parasitic battery drain for your towed vehicle, ensuring it's ready to start upon reaching your destination. Key benefits of using Blue Ox towed vehicle charge lines: * Helps prevent the towed vehicle's battery from draining during long towing periods, especially important for vehicles with parasitic battery drain * Maintains battery charge—supplies current from the RV's battery to maintain the towed vehicle's battery charge, keeping it healthy * Ensures readiness for the towed vehicle so it's ready to start upon reaching your destination * Requires a minimum of 13.3 volts to enable charge from the RV to the towed vehicle battery—charger requires a ground to exist between the towed vehicle and the towing vehicle * Only charges when the RVs engine is running—isolated when not charging * Thermal protected—protects from overvoltage and reverse batteries * Pulse with modulation (PWM) overcurrent and temperature regulation * Direct Current (DC) load current continuous 15 amps Show Less
