SECTION 4.15 Vehicle-to-Cabin Charging System

Gladiator cabins are equipped with a dedicated DC-DC charging system that charges the cabin living battery safely while you drive. Unlike a standard trailer socket, this system uses a heavy-duty 3-pin connector together with a DC-DC charger. It delivers more stable charging, reduces voltage loss and improves efficiency, especially in modern vehicles with smart alternators.

How the system works While the engine is running

The vehicle starter battery supplies power to the cabin through the 3-pin connector. The ignition signal activates the DC-DC charger. The DC-DC charger regulates the incoming voltage and converts it to the correct charging profile for the cabin lithium battery. The cabin living battery is charged safely and efficiently as you drive.

When the ignition is switched off

The DC-DC charger automatically stops charging. The cabin battery and the vehicle starter battery are electrically isolated from each other. This protects the vehicle starter battery from accidental discharge.
