Check out Amazon. When you do, be sure to look at all the various options as prices can vary quite a bit between the packages. Best one I found is 16 AA's at $39.xx
I've ordered from them a couple of times, fast delivery and best prices I've been able to find.

Rodney,
I have not been able to find Eneloops with tabs. Have you?
Have you tried soldering the tabless batteries?
Were you successful?
Any suggestions on the process?
Thanks,

The ones I got do not have tabs. I did solder up one 8 cell transmitter pack successfully and one 4 cell receiver pack. I used desolder braid for the interconnection with no problems. I just tinned the ends of each cell first (use at least a 40 watt or bigger iron and clean and flux the area first) and then joined the cells with the desolder braid leaving enough play so that vibration would not cause a failure. If you find a reasonable source of cells with tabs, let us know please.

Rodney,
I must confess I am not familiar with fluxing with electronics - plumbing, yes.
This is mostly because the solder usually has flux in it.
Your concept sounds solid. What kind of flux should be used?
Any recommendations? Where to buy?
Thanks,

I use Kesters Soldering Paste. It has been so long since I bought any I do not remember where I got it, probably Radio Shack. A small tin will last you for years unless you are into heavy production. Just about any soldering paste will work as long as it is not an acid flux like often used in plumbing. I believe it is rosin based but am not sure. I think most hardware stores also carry soldering paste, just make sure it is for electronics. Yes, lots of solder has a flux core but it is often not enough to do an adequate job on some of the larger surfaces. The main thing for a good joint is to have the surface meticulously clean with no oxide or corrosion on the area to be soldered. If you think there is any, use a fine grit emery cloth on it then wipe the surface with alcohol or thinner before fluxing it.
