[Abbenay] router battery pack

[Lars Sjögreen]

Using batteries (esp. rechargeables) in parallel is not a good idea because
the bad batteries tend to leech off the good ones making them bad too over
time.
Have you considered using a 12 volt led/acid car battery (or something
similar <http://www.clasohlson.se/Product/Product.aspx?id=134951217>) plus
some kind of voltage
regulator<https://www.elfa.se/elfa3~se_sv/elfa/init.do?shop=ELFA_SE-SV#toc=19819;>or
switching
regulator<https://www.elfa.se/elfa3~se_sv/elfa/init.do?shop=ELFA_SE-SV#toc=19852;https://www.elfa.se/elfa3~se_sv/elfa/init.do?shop=ELFA_SE-SV#toc=19852;>
