The BMV712 is a great battery monitor and if using VRM it allows the graphing of SOC over an extended period which is very useful to see. The History page is helpful on the BMV but it would be so good to be able to see parameters like SOC historically by just using the Connect App, similar to the VRM display but only using the Connect App. The MPPT controlller lets you see the charge parameters graphically historically and it is a great feature. I realise this would require strorage on the BMV and a change to the Connect App but it would make a great product even better as when on your boat you would be able to see the charge discharge cycle of the batteries very easily.
