First Andy and ionic seems to be looking into this as a application/app problem and a update to the app possibly will fix this waiting to be told. But One of my 12v 100ah batteries is not connecting to the app. The app is working for my other 2 batteries.(1 12v 100ah trolling/ 1 cranking 12v 125ah) I was wanting to know if or how many other guys have see or has this happen too.
