How to Effectively Charge RV Batteries While Driving

Quick update (3-2021): In this video, we send the charging current through the 7-way connector. This will work, but not optimally. We have since noticed a small drop in voltage between the DC to DC charger and the house batteries on the trailer. Instead, we recommend connecting the DC to DC charger to the battery bank using quick connect cables such as Anderson connectors.
https://shrsl.com/2vj94 Note: You will need 2 of these cables -- one from the charger to the battery and one from the battery to the charger, using the quick disconnect when you separate your tow vehicle from your trailer.

In this video we'll cover:
1. Why your RV batteries don't get an effective charge while you drive.
2. How the DC to DC Battery Charger works and integrates into your towing vehicle and RV system to reduce charging times.
3. Our step-by-step installation of the Battery Charger into a 2017 Toyota Highlander that tows a 22 foot Micro Minnie Winnebago Travel Trailer.

Brief Overview:
Most travel trailers connect to their towing vehicle with a 7-way plug connection, which provides power to the trailer. At only 5 amps, this isn't enough current to effectively charge the trailer batteries.

With a DC to DC battery charger integrated into this system, it acts like a pump to electronically boost the voltage (pressure) and amperage (flow) coming from the starting battery to provide a more effective charge to the RV batteries and greatly reduce charging time. The maximum amperage with the DC to DC battery charger installed is closer to 20 amps, rather than just 5 amps with a trickle charge.
