Here is the situation. 40amp Renogy DC to DC charger. Travel trailer with two 100ah Renogy Li batteries. Truck is Ram2500 with 220amp alternator. 4g wire to and back to charger located in rear of truck. About 20' each run of wire. This week camping in well shaded campsite. 420 watt of solar did not keep batteries charged. My battery bank was at 60%. Moving from one campground to another, three hour trip. I turned on the Dc to DC charger and hit the road. The shunt based Renogy battery monitor was only showing 15amps going into the batteries. After three hours of driving, the batteries were back up to 90%.
Why am I only seeing 15amps to the batteries? Any help appreciated.
