Looking to start your 4x4 battery upgrade and not sure what charger will handle your power requirements? Let Shaun Whale walk you through the key differences between smart battery isolators and dc to dc chargers.

If you tow an RV, camper trailer, horse trailer, boat trailer, or work trailer, chances are you rely on an onboard battery to run lights, pumps, fridges, winches, or tools. But keeping that trailer battery properly charged while you drive isn’t always simple. That’s why many setups now use a trailer battery charger.
If you’re into camping, touring, or overlanding, chances are you run accessories like fridges, lights, or inverters when your vehicle isn’t running. To keep these powered without draining your main battery, many adventurers install a dual battery system.
Towing a trailer safely is about more than power—it’s about control. Whether you’re hauling a camper, boat, livestock, or overlanding trailer, stopping safely is just as important as pulling the load. That’s where an electric brake controller comes in.
REDARC Electronics, the industry leader in mobile power management and towing, will showcase two major product launches at SEMA 2025: the Tow-Pro Link and REDWorks Power Panels.
