[SPARCbook] Huge Battery

[Ken Hansen]

Nice large batteries are available, but in nice cases can get expensive (see
www.igo.com and other laptop accessory shops)...

Many Ham magazines (radio - not pork) list 12 volt battery packs for remote
communicating that might suit your need for "luggable" power...

HTH,

Ken
