Hi Flybob,
At the moment I design the I/O modul. This modul have additionally 4 analog inputs. They measure from 0-20V. (I have expand them from 10 to 20V) you can use up to 4 modules on an MCS so you have up to 16 analog inputs and you can measure 16 battery´s …. ;-)
There Isn´t a power button in the case. The MCS-board has an terminal where you can connect a extern switch. If the Terminal has 12V the pi starts. If the Terminal has 0V an gpio of the Pi switch to 0V and the pi shuts down by a script. after 40s the Power supply on the MCS shuts down. So now you can power the Terminal back to 12V via an extern switch and the Pi starts again...
