[Abbenay] router battery pack

[Leo Nordwall]

Hmm, perhaps that would diminish the portability of the device. If possible,
I'd like to go for something leaner. A regulator and a 9 volt battery (or
two?) maybe could do the trick? Battery pack building is something new for
me, so I don't really have a particular plan in mind, other than portability
and standardization (easy to charge or buy cheaply).
