I have a Jeep Cherokee Trailhawk to be tow behind my Challenger. I have a roadmaster towbar and brackets. For a brake I plan on getting RVibrake but plan on using a wireless tow brake light. I am worried the RVibrake running down my Jeep battery. Any thoughts or suggestions?

Thor ACE towing a '15 Jeep Wrangler w/Blue Ox tow bar, base plate and wiring kit. As of this trip using RVI Brake2. Easy system and seems to help brake.
I plug into the hot 12V plug inside center console. Have only towed one day at a time 2-4 hrs. So far no issues with battery life.
My Invisibrake charges the Jeep battery from the motorhome... If your braking system doesn't - I would recommend something like what Bruce mentioned. On a long trip, you can certainly drain the battery if not being charged.
