I have had two (2) Interstate deep cycle RV batteries in my teardrop for about 4-5 years now. I haven't really used them for the purposes ie; ceiling fan, several Led lights or usb/cig plugs. Most of the time always running off campground power. This Teardrop is always plugged in and garaged so the only time off power is traveling. I just recently installed a 100 watt solar panel and Renogy hook ups. Problem when testing outside in direct sunlight, just having fan on draws battery down within minutes! I have attached several pictures that were taken today in a 10 minute period. I need some expert experience advice. The pictures are in the steps on the Renogy control. The first picture is when plugged in.
