Charging RV Batteries with a Redarc In-Vehicle BCDC Battery Charger
Question:
I have a 2018 Ram 3500 dually and wanting to know if I need a dc-dc charger to charge my new lithium batteries I installed in my rv. Im not sure if I have a smart charger and if I do would I need a dc-dc charger? When I have my truck running everything off Im getting 13.67 volts after about 10 minutes with the truck running. Thanks

The Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 25 Amp # 331-BCDC1225D will allow you to charge your new lithium batteries in your camper using your truck. It has a dual option to hook up to solar panels that have 9-32V power output to charge your batteries as well.
Since a lot of newer vehicles have smart alternators which don't allow a high enough voltage to charge the auxiliary battery you'll need the BCDC Battery Charger because it will boost the voltage to ensure proper charging.
I've attached an installation video that offers a ton of information and goes step by step on installing this charger.
