I have a smart 150/60 charge controller. Initially it was set on rotary dial 2 for my AGM batteries. The battery manufacturer wants a third of a volt less for the absorption and float. I created a preset and it doesn't work. I tried expert mode and that didn't help either. Am I doing something wrong? Is this a bug? I'm trying to reprogram it with Bluetooth which is supposed to override the rotary dial. Thank you for any help you can give me.
