RadioShack PRO 197 scanner with internal Li-Ion battery pack. I used four 18650 2600maH protected Li-Ion cells. It operates for 13 hours and can be recharged through the 13.8 volt jack on the back of the unit. Photos of the mod can be viewed at www.radioreference.com - at the RadioShack forum. If the post is no longer current, do a search for threads done by EvilLithiumMan. Pics can also be seen at http://evillithiumman.imgur.com and on Flickr (finally).
Thanks for watching.
Howdy Howdy Howdy. I like what you did by installing an internal battery. Would like to see the insides, maybe the "How To" step by step with the same battery and supplies you used. It looks like a clean install though. Really Nice Job.
