I'm sure Radio Shack makes just the adaptor you need, a variable 12V DC to 9, 6, 4.5, 3 and 1.5V, with the cig. lighter plug. If that's not practical, you could use a 9.6V Zener diode or just a 78 series regulator (I'm not sure if they make a 9.6V one but there should be something close). It is a three lead device that looks like a transistor, one lead goes to 12V (or whatever you have) another to gnd. and the third is your regulated voltage with reference to the same ground as the input.

You can use a LM317 voltage regulator, they are adjustable unlike the 79 series parts. It will require a couple of resistors and possibly a small capacitor or two but should be able to be built for 5 bucks plus the cost of a case. I will design one and get you a schematic and parts list hopefully sometime tomorrow.

Have you tried the 9.6V Tyco R/C Care batteries? I didn't know if they would work or not. Just in case the adapter doesn't. Wal-Mart even carries variable cig plug adapters, so you may be able to get one there too. Just some random thoughts.

Shadowstar, the problem with doing a resistor network is that as soon as you add the load it will change everything. You could design a resistor network that would still work but the current draw would have to be a constant value.
T A Sam, I emailed you a schematic and parts list, let me know if you need any other info.
