I know with our Victron battery monitor we needed to enter the amp hrs and I tweaked the Peukert number based on the battery specs. @marycompetti, did you make any adjustments? (View Post)
Back when the factory was allowing customizations, we had them remove the USBs and replace with 12 v sockets. You can also cut the wires to the USB if you wish to eliminate phantom draw. (View Post)
My understanding is the USB charging ports are not long lived. Unless you think it is an actual circuit problem... I am not familiar with the location of the USB in the new S models. (View Post)
