Keeping Your Battery Charged While Using The Roadmaster Invisibrake

Question:

I have an invisabrake in stalled on my f150 and it trickle charges the truck as long as I have the lights on on the RV. I resent installed the same setup on my 2021jeep wrangler but after a 4 day trip the Jeep battery was low. I was wondering if the installer missed something

The Roadmaster Invisbrake # RM-8700 will trickle charge your battery with 2amps (only while the RV's headlights are on) to supplement the battery power it's using to run. You probably have more things running off of your battery in the Jeep than you did in your F-150 and that's what caused the battery to drain.

I recommend getting the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 to help keep your battery charged.
