Battery meter light went from green to red yesterday. It was not a flashing red, just continuous red. Motor kept working. I was fishing a river with heavy current on spot lock. I had been using SL about 15 mins steady. The light went back to green after i stopped using SL for a while and was floating the river. Eventually went back to red again later as i had used spot lock for several minutes at another spot. Nothing about a red light in owners manual .
