Battery drain can catch you off guard when you're flat towing. The CURT RVi Battery Charger+ keeps your toad's battery charged while you drive, shows real-time status, and helps you avoid the frustration of a dead battery when you unhook.
Many towed vehicles draw power while being flat towed, which can slowly drain the battery before you ever reach your destination. The Curt RVibrake Towed Battery Charger+ is designed to prevent that unseen parasitic loss by helping keep your towed vehicle's battery charged while you drive.
By maintaining battery charge during travel, this system helps you avoid the frustration of arriving with a dead battery and makes it easier to unhook and go when you reach camp, the trailhead, or your next stop.
Multi-color LED indicators give you quick feedback on charging status, towed vehicle battery voltage, and RV voltage levels so you can confirm the system is working at a glance. The charger provides up to 10 amps of charge and includes built-in connection protection to help safeguard your electrical system if installed incorrectly.
It is compatible with all 12V batteries, including trailer batteries, making it a flexible solution for a wide range of flat tow setups.

Thank you
Easy to install and works perfectly
First trip out with new equipment. So far so good.
The Curt Towed Battery Charger (part #RVI74FR) is one of those small add-ons that makes a big difference when you’re flat towing. A lot of supplemental braking systems draw power from your toad’s battery, and without a charger you can end up at camp with a dead vehicle that won’t start. This kit keeps your battery topped off the whole time you’re towing by pulling just the right amount of power from your motorhome and feeding it back into the towed car. It’s designed to work seamlessly with RVi brake systems like the Shadow 2 and RVi4, so everything stays in sync without you having to think about it. The setup is simple, it’s lightweight, and it gives you peace of mind knowing your vehicle will be ready to drive as soon as you unhook. For RVers who do long hauls or run accessories in their toad, this charger is a must-have for hassle-free trips.
Easy hook-up. Works great
A must have item on flat tows. Great product. Highly recommend
Love the rvi4 brake. But nowhere was it mentioned that you needed to buy two additional items to make the display work completely. Battery charger and breakaway modules. I feel that they should have been part of the boxed kit. Especially for the money. I ended up buying the battery charger but I’ll watch my camera for a breakaway for now.
Quick delivery and good communication regarding my order.
Should solve the problem of draining the Jeep battery when towing long distances.
