One thing I know and that I did wrong is when you want to make a 12volt power supply (A 9volt and 2 x 1.5 volt) the 9 volt killes the 1.5 baterys fast!!!!

9v batts good for onesie and twosie shooting.
You mean you're getting one or two shots off the batteries?
No not necessarily. My point was if you go out for an extended afternoon of shooting, your 9v fan batteries will be groaning after an hour or so, needing replacement. RC batteries will have better life plus a simple recharge will have them ready to roar again the next afternoon.

Bingo. Because the batteries used in R/C applications have pretty good amp-hour ratings.

Ahh ok well that makes sense. My cannon has the room to carry the charger, rc batteries, and spare 9vs in case I'm especially mad at the potatos that day :wink:

I have 2 9.6v packs, but one seems to be missing...
