The power is yours.

There are not many things worse than a dead towed battery when flat
towing. Many towed vehicles today have a large current draw on the
battery when towing. Towed Battery Charger Plus will prevent
this unseen parasitic loss on your towed battery. With LEDs that
give feedback of your towed battery and charging voltage there
is no more need for a charge line that gives you zero feedback.

Now that's power!

True Charging: This is not just a trickle chargerTBC+ Charging Gas Gauge

All towed vehicles are not created the same. With so many varying types, each one draws different amounts of power on the battery when in tow mode. The Towed Battery Charger Plus is an on-demand system that not only trickle charges vehicles that have little draw, but can charge up to 10 amps when there is a high parasitic drain on the battery when flat towing.

NOTE: Towed Battery Charger Plus is compatible with all 12 volt batteries including trailers. NOT recommended for 2019-present Chevy Equinox.

The multi-colored LEDs on Towed Battery Charger Plus give instant feedback on proper installation and performance. You won’t need a multi-meter to know the towed battery voltage level, charging status, and voltage levels coming from the RV.

Now with Connection Protection, Towed Battery Charger Plus guards against damage to your electrical system if it is installed incorrectly, and prevents your motorhome from draining the towed battery.

Toad Battery Charger

After purchasing a new unit followed steps provided by RVI to wire the unit. It took me about 15 minutes to complete and as advertised worked very well.


My second one

Well, round 2 is better than round one. When not connected to the RV, I have learned to disconnect the RVI charger since it still draws from the car battery. I have already replaced the car battery once and realized that parasitic draw was the culprit.


Finally a battery charger that works

For the first time in 5 years our 2018 Equinox is charging while being towed. In addition to adding the RVI charger, we changed the charger wire from a #12 to a #8 so we are only losing a a fraction of a volt between the MH battery and the car plug.


Works great, easy to install

I have a Jeep Wrangler used as a toad, battery would run down after multiple days of towing. I installed the battery charger, and it seems to work as advertised. I haven’t made a multi-day towing trip yet, but from the status lights, it indicates it’s doing what it is supposed to do. I installed this myself. It was relatively easy, my biggest “problem” was grafting the ground into my 6 pin connector. Had to make a pigtail, to get two wires into one hole. Just to make it harder on myself, I chose to solder my connections, and some shrink tubing and electrical glue tape, and finished it off with dielectric grease, as I found some early signs of corrosion. Good product, seems to do what it says, pretty easy install for a DIYr.
