Saving you a lot of time and effort, and maybe providing some security as well, here's a link to an 1100 maH 8 cell transmitter battery.

By the time you try to get those cells soldered end to end and shrink wrapped, you could have spent only $23.00 on this one and be done with it.

It's about half way down the page.

There are others available, but I like Radical batteries.
