[Abbenay] router battery pack

[Lars Sjögreen]

If you need 2,5 A you'll run out of juice pretty fast with batteries. NiMh:s
(1,2 V) typically have around 2-2,5 Ah in them which means that unless you
have a /lot/ of batteries you'll need to change batteries often.

LiPo-batteries have more power but are harder to take care of. You can't
mishandle them (overcharging, letting them go empty etc).
