I'm not sure how many people will build their own EduCase with the full Arduino control but I know if I go to a production version I will want some functionality to protect the case and batteries. I updated the Aurora firmware to V1.2 for the system alarms.

You can see some of the updates in the code here:

These to will initiate a warning and alarm via the LCD display if the battery voltage drops too low or the batteries themselves get too hot for any reason. From there it is easy to use the integrated relay to shut the case down in the vent of a severe over temp condition (not currently done in the code but will be added later)

You can find and browse all the new code and mods on Guithub at the links in this project description.

Cheers! Eric
