I was JUST talking about a 9 volt mod with a regulator to take it down to 5. I found these at 520 mAh: Rechargeable 9 Volt Lithium Polymer Batteries: Efficient
Nice to meet you JRWReich,
Yes theses seem very nice, just wish 520mAh was a bit higher. But given that this is new gel technology they just may do the trick.
If you know anyone who build a mod box using these please let know.
Thank you,
