my bmv 712 smart defaults to 240 h in the time to go screen if i set the battery capacity to anything higher than 340 h i currently have a 600 h battery bank but it will show 600 h in the time to go screen i have zero load on the system
The default to 240h occurs if the time to go is more than 240hr, so if you are drawing 2A from a 240Ah it will display 120h to go, 2A from 480Ah = 240h to go, 2A from 600Ah = 240h to go. It avoids divide by zero errors.
