Home Built Power Battery Power Pack
I have used rechargeable batteries in my Lynx II in the past. For some reason the actual rechargeable-type AA batts are a tad thicker in diameter, meaning it's a very tight fit to insert 6 batts in the LYNX II batt compartment and it is hard as H*ll to get the batt door back on (or back off).
That got me to thinking, how about constructing my own battery pack. Get a 6-cell battery holder for AA batteries, then wire a barrel-type connector lead to it.. Wha la, cheap-o battery pack.
Battery Box can be purchased for a little as $2.50 on eBay. Or for about $7 on Amazon. The right-angle power connector can be had at Console5 for about $3. Simply solder the wire of your choice. The wire I used was just what I had on hand. I am getting about 4 hours of play on Energizer Rechargeable batts. I used to insert them into the unit, but it was VERY tight fit and stressed the Battery cover. So, now this is what I use.
