Does Blue Ox Patriot 3 Portable Braking System Require Connection To Vehicle Battery


Does the cars battery need to be connected in order for the unit to work? If I leave the battery connected and in accessory the battery dies. I’ve been using a power pack but do not feel the brakes working


Helpful Expert Reply:

The Blue Ox Patriot 3 Radio Frequency, Portable Braking System - Proportional # BRK2019 needs power for proper function, so it does require a direct connection to your battery which isn't an issue on your 2015 Ford Flex. Some vehicle require a separate connection to the vehicle using # RM-9332 to avoid the other features drawing power. The Patriot has its own battery for emergency use only so you still need a power supply.

Since you are worried about draining your battery, I recommend you use the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 to allow the motorhome to charge the vehicle battery while it is being towed. This connects to the 12v power pin on your motorhome 7-way. If your motorhome doesn't have that power, then I recommend using the Roadmaster Battery Charge Line Kit for Motorhomes # RM-156-75 and if you need the 7-way use # C57672 as an adapter.
