Hey Llyod, thanks for reaching out!
Both the Brake Buddy Classic 3 # HM39494 and the Brake Buddy Select 3 # HM39524 have a 12V power draw of 15 amps. Pretty much any braking system like this will drain a battery during a full day's use.
The great thing about both kits is they come with a car charger so you don't have to worry about your battery being drained when you get to your destination!
Do you still have your battery charging part of the system? If not, you can pick it up with this part # BB54FR.
What vehicle are you planning on flat towing?
