Toad charge systems prevent your flat-towed vehicle's battery from draining while you drive. When you flat-tow (dinghy tow) a vehicle, its electrical system powers the ignition module and computers even with the key off, slowly depleting the battery. Charge line kits connect your motorhome's charging system to your towed vehicle, maintaining the battery so it starts immediately when you disconnect at camp.

What to Know Before You Buy

• Basic charge lines provide continuous charging; smart systems with isolators prevent your towed vehicle from draining the motorhome when parked.
• Most kits use your existing 7-way connector's auxiliary circuit; some run a dedicated wire for higher charging capacity.
• Vehicles with complex electrical systems may need additional components to manage charging properly.
• LED indicators help confirm the charge line is working—you don't want to discover a dead battery at the campground.
