This DC-to-DC battery charger lets you take advantage of extra energy generated by your alternator to charge a battery bank in your RV or overlanding vehicle. We recommend this one for vehicles with alternators generating 40 amps of excess power.
WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!
