Hi there,
I've build my own webserver (thanks to Robert Moskowitz) with the cubietruck. I've bought a LiPo UPS (http://www.pollin.de/shop/dt/MTU3NzkyOTk-/Bausaetze_Module/Entwicklerboards/...)
My search at the internet found, that with Cubian or other Debian-based OS there is way to monitor the powerpack with "cat /sys/class/power_supply/battery/uevent".
How tho manage it with CentOS? There is no such directory.
Mit freundlichen Grüßen Andreas Reschke
